Invalid or Expired Security Certificate?

Provided you know what the possibilities are, in the first place.

HOLY COW!! I have been looking for a fix to this very same problem for days!! I have worked on pc's for years and have been stumped!! I did everything suggested by everyone from tech friends to Microsoft. I compared my laptop settings to my PC's. I tried altering the installed JAVA. Everything short of formating and re-instal of Windows XP Pro. (Im not THAT anal) Nothing worked! Low and behold after reading your posts I check the date of the laptop and it is off by a year!!! I make the correction and the problem is gone. All I can say is....THANK YOU!! Is there any answer that cant be found on google?? LOL

Just today I started having this same problem and it was making me crazy... turns out I accidentally changed the date yesterday. THANK YOU!!

What if the date is not the problem?

I found the same problem. I checked the date and time and they there correct! Somehow I managed to set yesterday's date - and the certificate became valid ! :) Valid for that day. I think that is for the different time zones between USA and Europe.

OMG! This has been bothering me for TWO DAYS! I have gone through articles on SSL, ran countless virus and spyware scans, and uninstalled a VARIETY of software packages. FINALLY I found this site and I went to check the date -- some how the system was set 4 months in the FUTURE on this stupid machine and it was causing the error.

THANK YOU SO MUCH!

I'm naming my next kid Dave Taylor.

Sincerely,

Robert Griffith

Wow, I'm glad there is finally a solution to this. Simply a date/time change, never would have thought it. Thanks for the solution (to the man who wrote about it), and Thank You Dave for posting it. =)

Thanks for keeping this post alive. I have been working off and on for several days trying to come up with the solution. Thought it was AOL's problem and kept looking there for some sort of fix. Finally tried a different search using XP and found you!!! Thanks for the help!!!

Thanks a lot, it work perfectly for me. Again Thanks, you saved my day!!!

I own a mac and cannot log on to google .com, gmail, or anything to do with google... it tells me there is a certificate problem and then that it is fixed and to reset the browser, i do so and bam, same thing again....i cannot access anything...please help me....

Holy cow. This drove me NUTS. Other sites suggested a corrupted IE. The only easy solution was to figure out Firefox or simmilar, for which I had no energy...then as I said to myself..one more click..I landed up here and... read the fix...then remembered I set the time back to make a freeware program work, never to restore it...THANK YOU ^THANK YOU!!!!
Excuse me while I go kick my own ass...repeatedly.

Dave,
as per other responses,would never had
worked out sec cert prob,many thanks.
Ted

Sadly, it doesnt works in my case. I tried putting the date back...putting it in the future..but still no change.

My computer was set 15 years in future. I am wondering who did that, it is for sure that was not me.

this problem is driving me NUTS!!

We all can't be this stupid. Something got in and changed the date in our computers. How many people here have replied to this? This is a bug no doubt. I just reset my clock because of daylight savings time, twice. I know I didn't reset my computer to 2008. I c'mon, the date set YEARS in the future said one person?

I am unable to connect two XP systems in a workgroup.The error showing is "The Network Path Was Not Found".I have disabled the firewall also.
I am not able to Ping also.Pls give any Resolution for this.Thank u!!!!!!!!!!!!!

thank you for giving me suggestion to chage date and time.

Same problem here. I kept checking my date and time and it was correct! Then I noticed that it still read Eastern Standard Time and not Daylight Savings Time. Ahha! Sync with Microsoft time (click on Internet time tab in date and time settings in XP) and all is fixed.

I can't believe my problem was solved by checking my date. You made my day!!! I've been trying to resolve this security certificate problem for 2 weeks and nothing has worked. I've had all kinds of help & suggestions from people who are pretty knowlegeable. Thought I was going to have to live with it until I purchased a new computer down the road. Such a "simple" fix for what has been a major problem.

Hello Every body, i was searching to Solve my problem, finaly i got this page address from google, my problem become ok by chaning my date and time settings.
thank u

Dave thanks for posting that security fix, and bless that dude that found the fix.so easy so hard.

I checked my PC's Date and Time settings many times. They are exact. Still I get the error. But I solved it by installing the SOME certificates manually in the Trusted Root Publishers List of IE. But I am unable to do that with Google website. It has an expired certificate which I cannot install. I installed only those which I use. I have Windows XP Pro SP 2 and IE 6. My Microsoft Update doesn't run and my PC is unable to synchronise with the Internet Time. This problems are related to the security certificates.

I am using Vista Pro and IE7 - I was having the same problem but the time and date on my computer was correct.

I did enable "Protected Mode" and that helped.

A million thanks. Typical; a problem solved by a few mouse clicks. Easy if you know how, and this sort of website tells you how!

Hmm... I'd love to buy you a chai, but I'm having this problem too, on my G5 Mac, the Mac Pro, and an iPhone all running Safari. The date on these machines is definitely correct. Anybody else having this problem??

Oh thank you so much for this post..It really helped me..I'm working with this problem for more than an hour..Then I've reached this site..Wow..Fantastic!The date was set on the 14th of October..Changed the time as usual..Poofs!It resolves my issue..Thank you so much for this post..Thanks for helping people like us..LOL!God bless you guys!

The system time on my computer is correct, but I am still receiving this error message every time I try to go to ANY website which requires a password. I use Mozilla. It doesn't even allow me to continue to the website temporarily. Any help would be very much appreciated!! Thank you.

>>>

Reply: Brian,what is the exact error message when you browse to the inet using Mozilla?Try also to check the security options under advanced tab of internet options..Just check the settings..Try to uncheck one by one then restart..If still the same,checked it back then uncheck another one,restart again..Just try and try..Good luck..

i had the same problem what gave it away for me is when i updated adaware and it told me my definitions were 3000 days old...lol

Hello:
I'm having troubles to login to OWA thru Internet because I get the error Message: "The security certificate presented by this website has expired or is not yet valid." .
The Certificate is ok in the server (FE) and the users are getting the error message trying to access from Internet only. The date/time is ok for the server and the links are ok (https) but the client users have problems to login. Any IDEA, CLUE, ???

Had same problem and it was an incorrect date issue as well. Problem solved. Thanks.

BULLS EYES.... IT WORKED FOR ME AS WELL !!!!

THANK YOU THANK YOU THANK YOU!!! I have been working on this and worried about this for a few days now. I was about to take my pc in to have it fixed.....you just saved me MONEY! For me I had been making some calendars and changed the year to 2008 and didn't change it back.......I have ran all kinds of virus scans and defrags and anything I could think of. I thought tonight I'm gonna search the problem and voila you fixed it!
Thanks!!!

OMG -- No one knew what to do. I followed all the "help" suggestions and nothing worked. One million thanks to your chap who figured it out. It worked for me! I almost didn't know where else to turn. And, thanks to you for posting it. I'll definitely check your site again!

constant security warnings were losing me sleep.BINGO your suggestion to check my clock [i was one year ahead]worked a treat. Merry Christmas on and all!!!!!

Date and time are correct. Problem persists. Just another MS bug? Definitions can be 3000 days out of sync? What gives here? Any further solutions for those situations where date adjustment does not work?

I can't believe it was so easy to correct those annoying expiration notices. Thank you, thank you, thank you! The date on my computer was one year ago. How does that happen??????????
Ah well, no worries now.

Thank you so much...I would have never figured it out on my own!!!!

I can just repeat the same as everyone else. After emailing IT people and getting mad because they kept saying it was coming from my computer and I tried everything that was suggested or I could find. Finally I stumbled onto your post. Thank you Thank you Thank you

Now how did the clock get changed is another mystery.

I found that if the site is being blocked becuase Vista supposedly thinks that the "Certificate had been revoked" you have the ability to go to Internet Options > Advanced and under security, uncheck the box that says something like, Check if the certificate has been revoked, and UNCHECK it.

I have tried everything here to fix this security certificate issue which I have been having for almost a week. Nothing is working. Should I do a system restore or is there a virus or corruption on my computer. I am very frustrated with this. Any help would appreciated.

Raelyn

I recently emailed you saying that I had tried everything and still had the certificate issue so I went to my date and time and checked it a second time. Well I missed it when I checked the first time. Sure enough the date was wrong. It was set to the wrong month making it one year ahead of the actual date. I changed it and no more certificate issues. I thank you so much for this site. It's amazing how my internet provider and computer company didn't even get it and I found the answer to the problem on your site!! Thanks a million. I really appreciate you!!

Raelyn

Thank u sir,

I too have a same problem of this security certificate.

i have changed the date and time in my system tray and now its working.

Thank u very much.

WOW!!! Incorrect date on my PC resulted in IE7 certificate errors. Many thanks. I am a bit embarrassed because I am highly technical and my forte is troubleshooting! Thanks again.

omg!!!!! Thank you thank you thank you I was about to throw this computer in the trash.

Unbelievable! I looked all over for this solution-no luck! After reading it, I wasn't even going to check-it just seemed impossible that I had the wrong date-NO-It somehow changed back a year! Problem solved-this is great-short-sweet-to the point and it works! All of my life should be this easy-thank you!!

Some programs or malware change computer date. it is good idea to regularly synchonize computer time with time.windows.com

When the alternate browser suggestion hadn't worked for me I had almost lost hope. Indeed my pc was set the wrong year. Thanks a million!

THANK YOU! THANK YOU! THANK YOU!
I've been struggling with the same problem for two days -- adjusting security settings, etc. However, my computer's calendar was only off by 1 month! How, I'll never know.

VERY VERY THANKS, I THOUGHT IT WAS VIRUS....BUT I CHANGE TIME IT WILL OK

Hey Dave I could use your help! When I try to enter my e-mail account which is on hotmail i get a message telling me that the certificate is revoked! It doesnt even let me continue to the website anyway!!! Im goin nuts over this so if you could gimme a hand it would be really appreciated. If it helps im usin Internet Explorer 7 on Windows XP Media Centre. Cheers in advance. Sean

I can't believe I stumbled onto this forum! I have had that stupid security error for a month and could not figure it out. Just about to trash this laptop because I've had other problems with it....and hallelujah!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Thanks soooooo much for your help!

I changed the date and its STILL NOT WORKING!!!!!! whats wrong??? im using IE7.....

The fact that this thread has been going on since April 2007 means its really helping. I too want to join the many gratefulls. Thanx alot, I hope to remmember this the next time I come across it. If I dont remmember I will definately find this link again :)

Thank you very much, it work perfectly for me. Again Thanks a lot, you saved my time!!!

Thx. This Silicon Valley girl is greatful.

I am using IE 6. I already have the correct time and date for my computer. I adjusted the browser settings but i am still getting the same pop-up for the security certificate. I already disabled my security suite as well. What else can i do? Anyway, the security certificate only pops up when i try to sign in to my msn email.

Thanks for the solution to the certificate error -- so simple!

I have the same problem with websites security certificate saying certificate has expired or not yet valiD. Took it too cumputer repair shop they said it was my date and year not set properly but i still get it HELP PLEASE

when back and reset the time and date this time it worked

my date was set into the future. AFter setting it, it works good now.
Best part is cox said I have a problem with my computer and will charge me $99.

hello every one
this is the same way i fix this same problem for other people.
but some times this does not work if you install windows XP with service pack 1 then up grade the service pack to 2 whilst having IE 6 installed
then upgrading IE 6 to IE 7 some times this causes
a glitch in the pc so thay should uninstall IE 6
then install IE 7 .
i have found this to work in some cases that the other way does not work.

Hi Dave. Maybe you can help me with this problem. Whenever I try to go on a site that requires secure log-in, eg. bank, ebay etc. I get a security warning pop-up saying there is a problem with the sites security certificate. It says "the security certificate has expired or is not yet valid" and gives me options to continue yes/no or view certificate. I am operating palm t/x.

This error message comes when I access Microsoft Outlook 2007. After that I recieve a delivery failure message when i try to send my mail my mail using outlook. I use Ms Exchange 2007

Still a terrific post!! I had the same problem with a computer I bought from E-bay. My date was set to January 2001 I reset to 10/30/08 today's date and everything worked like a charm. I wouldn't have found this answer if it weren't for yahoo and my laptop!! Thank you so much, it does drive you crazy.

Larry,,Mi.

Amazing....absolutely AMAZING!

Great answear! Thanks a lot.

en effet. j'ai modifié la date car mon pc rencontre des problemes avec system.exe.

C'est la bonne réponse a mon problème. :)

Thank you so much.

Ah people whose computers' time changes without notice, should replace their cmos battery..

OMG! I cant believe it, i had this problem and all it is was that the date was changed.

Thank you Dave!!!!! This problem has been haunting me for days. I was worried someone out there had all my private information. Turns out the date on my computer was just set back a year. Thank you thank you thank you!!!

So how do I change the date on my ocmputer so I can fix the invalid security certifdicate problem?
Thanks, Joe

Hello DAVE!

Thank God for this post! I have been working as a tech.support and this has bugged some of my customers for their email access... Tried it and it worked!

Happy New year! Thanks again.

After 1 week of the bloody security certificate glich,I stumbled on your site. Ayupper! Worked like a charm! Many thanks! Jim

Thank you Dave my grandson had changed the date to 2099. Thank you!!! Certificate error solved.

OMG you guys are awesome! I had the certificate problem for the last week and for the life of me could not figure out what had changed or where it was coming from. I tried everything security related that I knew of and was plain out dumbfounded. Turns out the date in my computer was February 2008, once I corrected that walla no more problem.

thanks to that genius ..the solution is so easy yet so hard if she didnt shared it...cost us some dollars again to bring it to the shop for fixing..thanks greatly! it was a real big help..

I have had this problem for a while so thanks alot!, its because my computer never keeps the time and date because its battery has died. :(
I should get a new one really.

Thanks again
James

thank you for giving me suggestion to chage date and time.

This fix is genius, I've been struggling with the same problem for days. Thanks for keeping it posted.

WOW thankyou

this error scared the bajezzes out of me i was so scared my info was being leaked...even contacted paypal, and ebay regarding it was SOOOOO Scared...then decided to google the first part of the error...omg...what a life saver.

Thank you dave and the original poster.

Wonderful site you have going on here...glad i found it.

Kim

Hi Dave.......
thanks you very much.i was also facing the same problem. i updated the security certificate and change the different internet options and studied the SSL state but nothing worked. it will be so simple i never thought of it. thank you very much

THANK YOU. The invalid security certificate problem has plagued me for months. You solved the problem by telling me to correct the date. God bless you!!!!!!!!!!!!

I have had this error for one month, we have tried everything!! I called my internet provider who tried troubleshooting, they couldn't fix it. They referred me to Microsoft, who were no help, then wanted to charge me money... i said no thanks. I then decided to google and found this website, all I had to do was change the date and I was set. WOW! I would have been so upset if I paid Microsoft to tell me to change the date on my PC to fix this problem. You all are awesome! Thanks for alleviating so much stress from me!!!

I had the same problem with the expired certificate issue. Instead of getting upset right away I took a deep breath. Usually this is when I start a series of technical "Hell" days trying to resolve a problem.

Thank you so much for posting this solution. It literally saved me weeks/months of stress.

I would still like to know how the date got changed.
Many, Many, Many, Thanks, Karen.

Ingeneous!!! I was living way in the past! Like many of the other posters I was concerned my computer was being tapped into. Many thanks to the Sherlock sleuth and Dave for sharing on this website.

I have WIndows XP, Sp2, IE6. I still get an invalid certificate after syncing time with server. Any ideas???

Bam! Thanks!

HAHAHAHA...Gosh!...I even rebooted Windows Vista...such a simple solution! HAHAHA...as a future computer technician...I will remeber this forever!

Are you serious, the date? That fixed it.
Thx a million Dave.

Thanks for the help

Dave: Thank you for sharing this solution with us. I am glad I found your site, as this was a real time problem for me. I missed a chance on an auction, but won't miss the next one.
Regards, ~Dick~

Hey Dave, I wish I could be thanking you right now, but unfortunatly I can not! I read through your solutions and I have tried everything so far but everytime I log into my email, it brings up the "this websites security certificate has been revoked" error. I am going crazy because my email is my lifeline! I know you will be able to help me.
Thanks!

everytime i click on something to open it freezes . then the internet explorer has to close.

when it does it says something about add ons . i have no i deal how to fix this. can you help me?
when my computer freezes i have to shut it off on the bottom thats the only way it will shut off. thank you arlene

Thanks I cant believe it that is all it was the date. My wife is an I.T tech and she never ran into the problem before and now i can tell her i fixed it lol. Thanks for all your help.

This was the problem! Thanks!

Lol , Same here. I’m pretty god at fixing computers and I tweaked IE several times to try and get the “security certificate warning “ to go away. Nothing worked! Finally one site said that if your running IE 7 you’ll need to go into tools (top button on IE page)\internet options\advanced (over on the upper right side of the box) once in “advanced� scroll down and check your security boxes.

Anyway that wasn’t my problem either and I thought I had a virus. I was just about to reload MS Windows and then I found this page. My clock was off too. My date was off by 5 Years after I reset c-mos. Thanks You Guys So Much. You certainly have saved me a good deal of what would have been wasted time. Hail Dave!

Dave, thanks so much. So glad I found this site, I was going crazy!
Alli

Finally. This was driving me nuts. I too thought it was a virus. My date was set 2 months in advance somehow. Now problem is solved. I'm gonna bookmark you Dave. Thanks

You're a life saver. I called the technical support guys at the company that I have the internet with and they told me to contact the administrators of the websites that I was trying to log in. Needless to say I typed my question on googled and there you were and the solution so simple. Indeed I had set the date three months in advance and thanks to you it's all working fine now.
Dave thank you very very much. I was literally pulling my hair out.

Not only did you just solved my problem, you have added two days onto my life!

I thought it was the 23rd because of this computer, and it's only the 21st, oh the chaos it has caused thus far...

Thankyou!

Placed a certificate on a server - and now we are unable to log into it. What can we do to fix this problem?

i did so many efforts from so many time....
thank u

Thank you so much for posting this solution. I was so puzzled to find I couldn't get to gmail this morning from this laptop, yet I could from the MAC and the PC. Thank goodness I found this, as the date was set to Sept 17 2008 and when I changed it today and set the time to Microsoft sync, the problem was solved.

What really puzzles me now is how the date and time got changed on the computer! Hmmm...is that elementary?

Thank you so much for this. I was bugged for a long time IE when it kept asking for a security certificate on trustworthy sites. I then realized that my computers date and time were off from this post and now the problem is fixed!

I HAVE SECURITY CERTIFICATE FOR THIS SITE HAS BEEN
REVOKED. THIS SITE SHOULD NOT BE TRUSTED.OK
THIS IS ON MY COMPUTER.IF I DO NOTE CLUCK ON OK.
THE COMPUTER WILL NOT WORK.

I had a network configuration that required a cert on the website (in IIS) on the server (a win 2003 box), AND on the firewall. This was specifically for the situation of the website functioning perfectly inside the firewall and not working outside the firewall. In fact, after a cert update, internal was perfect, but people outside kept seeing the old cert. But this page was useful nonetheless. Thanks everyone.

I had the error when I tried to access 3 new web sites for the first time.

I checked my date settings on my computer and found them to be correct.

I went back again and tried to access the sites in new tabs and the sites worked correctly.

Perhaps the server's time was incorrect and it reset the time on first access. Who knows, but now all three sites work and they did not on the first attempt at accessing them.

Thankyou from a friend,..... was getting house ready for sale, moved computer. trying to pay bills, leave for vacation. spent hour with this. (that i didnt have) not to mention the annoyance of a problem you cant fix and cant leave. I usually just reformat, guaranteed to fix any problem in less time in most cases, thankyou microsoft for the migrain headaches.
thankyou Dave for making everything right in my world again!

Well for crying out loud! I just installed new OS a few days ago and could not check my email. It was mindboggling..Then found your forum and checked date. Now I KNOW there's gremlins! Year read July 2025!.. After changing I found it a little hard to believe but my email was back to normal! Thank you, thank you, thank you!..Rob T

wow ! two days of going nuts! had my computer guy come over last night to try and fix it ! install ,uninstall,run this and that checking for the problem! woke up this morning and typed in security certifacate error in my search box! found this site.checked date and time.was off ,said aug/2008 changed it and all was fixed in less then 10 seconds !!!!!!!!!!!!!!! man i hate computers!!!!! thanks to the genius !!!

hi...friend...

im from phils..its been a long time since i havent able to log in in anywhere becoz of invalid security certificate.....i search on net and i found your site,thank you so much..i reset the date and now i can log in...keep up the goodwork...

Thanks for the info Dave. Wow! I was beginning to worry that my computer had a virus or was hacked when I tried to login to my e-mail accounts and pay some bills. Luckily, I came across this page. And to my surprise my clock on my taskbar was set to 2008. Once I reset it to 2009 no more problems! Thanks!

Thank goodness for your website. These security certificate notices have been popping up recently.
Tried checking it on my computer and finally decided to do a search online. Took around 10 seconds to find the answer! I couldn't believe that somehow my date was 2 years in the past! THANK YOU!

oh my gosh i stumbled on this website by accident. It was the best thing in my life(almost) I was ready to throw my computer out the window. Nobody I knew ever heard about certificate errors!!!! I changed time and date and whala!!!! I think I'll go put my feet up and have a glass of something.

Brilliant! Thanks for the answer Dave, however my problem has a little twist. My date and time changes every time I turn off my pc, which results in the same security certificate issues. Please help!!!!

Stuart, that's a classic example of having a dead battery on your motherboard. There's a tiny watchbattery that's used to retain date/time information on reboot or power down: if it dies, your computer is clueless on boot. Pop open your computer, find it, and replace it. Carefully.

Sir Ji My date and time changes every time I turn off my pc, which results in the same security certificate issues. Please help!!!!

LOL! I was having the very same problem with my mother's laptop and my first thoughts were the same as Dave's- I changed my browser security settings, downloaded Firefox and got the same results, ran my virus scanner. Then I searched the web and read this, mom's computer was set to a date over 6 Years ago! Thank you for posting this, I don't if I ever would have thought to check the date!

Just wanted to thank you so much for the info. I thought I had a virus or worse and it was just as you mentioned above the date was set at Jan. 2004 instead of Sept. 2009. Again, THANK YOU!

i cant access my google mail account and have tried everything suggested on the site, i still get the message.....websites security certificate what else is there to try...... its driving me nuts

Just worked. :)

I found the same problem with my computer, however I fixed it earlier today and just tried to log on to Netflix and it still did it?!

Dear Sir,

i updated the security certificate and also update time but is showing error. Please give me desired solution

Sir,

My date and time changes every time I turn off my pc, which results in the same security certificate issues. Please help!!!!

If you open up your computer, you'll see that there's a small watch battery on the circuit board. That's the date backup and if you're finding that you keep having the date and time reset, it's dead and you need to replace it.

Hey, it worked. All I did was change the date. Thank you so much. My sanity was at risk.

Thanks for the info on date and time. My computer time was Jan. 2004 and in October, 2009 aol.com was blocked until I changed the time close to the above date. Thanks a million, you saved me lots of time if not money. Lee

Hey All

Thanks for the heads up on the date and time - worked perfectly.

Just want to add, MSN and GMail checker also do the same thing - check for valid security certificates when the log in or check for mail. Im sure other programs do the same thing. If you get an error code from MSN or anything else regarding invalid security certificates check your date and time. Mine changed iteslf after i may have overclocked a little too much, had to fix the BIOS and set the month & date wrong.

Thanks again! :)

Superb!! Been having this problem for a while and tried everything, set the date to normal (didnt realise it had changed) and hey presto I am able to use the sites as normal, many thanks!!!

Wow, posted April 2005 and it's Nov 2009 and I have finally found my solution to this dilemma too (problem began last wk). Many thanks. I was not going to post here and say Thanks because of the 100s of other posts already out there. But, can you imagine the 100s of others like me, who have found help here and have not posted?

I had a few too many hardware changes to my pc that Microsoft didn't like it, so I had a Technician get me Microsoft re-certified. And, after all the changes, my BIOS was off, so the tech reset all that for me too. The 2 things he forgot to reset were the date and time!!! So, I went into my BIOS and changed them. What a miracle it is that I found this forum.

I can't get rid of the security certificate warning because I have lost all of my desktop icons, start/ menu button everything! There is no time at the bottom so I can't change it. How do I get my icons back???

Thanks..this was the resolution to my problem as well problem..it worked!!

Good solution and easiest for which I wasted my whole day thinking abt it and asking everyone, but none of them knew the solution,
Thank You For Your Suggestions.

I just woke up to what could have been a hugely frustrating problem, and I was envisioning many days lost to resolve, but fortunately your site came up with the simple correction which worked.Thanks to the guy who figured it out and thank you for sharing THANK YOU!!!!!!!!! Now I can return to life as it once was.
-Kristina

ah! thanks! this totally worked!

OMG Thank you Thank you Thank you!

Hello,

Gary

This problem has been the bane of my existence for months now!! I was afraid to enter any financial data or even access my bank record online because I was scared there was spyware causing this. After reading this blog i checked my date and it was set to the year 2025 for some reason?! Anyway, thanks a bunch!

"There is a problem with this website's security certificate".

I tried all things to rectify these error. Even unistallnig and reinstalling IE8. But at the end i found that my system date was in past and when i reset the date to current, the error seems to have vanished.so i geuss, date was the problem.

Same here...it gives me hell of of a time trying to solve this nagging prob...then I check my PC date,OMG it's Jan 9 2018...I dont know how it gets to this date...Just changed to current date and up to now the eror message doesnt appear

OMG THANK YOU!! I haven't been to my bank's website for days because of this! And I would have been shocked to think that they let their certificate expire!!

THANK YOU!!!!!!!!!!!!!!!!!!! MY MIND HAS BEEN NUMB FOR DAYS TRYING TO FIGURE THIS OUT! THANKS!!!!!!!!

THANKS A MILLION. Thought I was going to have to beg my husband to rebuild my computer after letting my kids on it and getting the "I told you not to let them us it" speech. This solution was very easy to find and even easier to use. Thanks tons.

I just want to ask, is it the same thing with the problem in yahoo messenger? I can't sign in..,:(
anyway, thanks for the info..., you are the greatest...

Thanks for your information.

I had this problem last year on a friend's computer. The clock was way out. I reset it and the next day it was out again. The problem was that the little back up button cell inside the computer was dead. Replaced it, reset the clock now all is well.
Had the problem with expired certificate with mine today but ONLY on Orange.co.uk. The clock and date were correct so I changed them to something random and then set them correct and clicked'apply'.... Problem solved.
This is a great site. Thank you.
John

Just looked at the posting from Chris at December 22, 2009. I think this might be a classic case of a flat back up battery.
John.

THANK YOU!!! It was the date. I never would have guessed that.

Hello. I have been having the same problem, except I use Firefox, the most updated version (I'm not sure of the number). I checked the date on my computer, and it is up-to-date. Any other suggestions, maybe?

Thanks.

A beauty!

my pc is also suffered from this problem of security certificate. i changed the date and it became ok.. now its going altogether correct.

Hmmm... Why would a laptop have a problem with the small backup battery? My understanding is that it doesn't have one of these -- it has the BIG battery! :-)
But, nonetheless, my date was very wrong (set for several years ago) and the time was one hour ahead - Eastern instead of Central.
Very weird, and thank-you so much for the answer! God bless Google!! :-)

Hi, Thank you so much for this fix - what a brilliant suggestion and worked a treat. I would never have thought the time and date would have any impact with the website's security certification. Many thanks!

I couldnt figure this expired security certificate problem thing out, but I come to this site and then felt like a fool for not thinking about checking the date on my system. This post and Daves answer worcked like a charm, but left me feeling a little foolish. But as long as my problem is solved, im a happy fool! Thank you bunches!

great -- the issue was simple -- my date was fixed to 5 yrs back!
updated it, everything's fine now!
Thanks a lot for a simple solution.

Hi Friends,

Iam facing the same security error when tried to launch my url using https://ip:4443/app url. My Server and client dates are same but still the same issue.
Iam launching the url from my webserver (oracle http server ssl)

Thank you! The date on my computer was wrong, too! What a relief!!!

Clyde.

Dave I am having this problem only with youtube ...but my date , time zone are right ...so now what ??? ...where do i get this certificate from ???

Thank you!!!

Ive tried setting the date but cant seem to get my connection back i cant access g mail but i can access Google and g mail log gin page. Ive tried resetting the date but nothing seems to happen. I'm still told my certificate is not secure or has expired.

You rock dude.
This was driving me crazy over a period of several days trying to fix it.

THANKS

Nice tech info! Great job!

I too had the problem with the expired security certificate problem. It was driving me crazy!!
I checked the date on my computer and it was 2007 so I updated it to the current year and all my problems are solved. I can actually go to my bank accounts now.

Completely unbelieveable. have spent 3 looooooooooooong evenings trying to download McAfee and staring at a blank window. Found this when i figured out that could be the problem no thanks to mcafee.

NOW ITS WORKING after changing the date.

THANK YOU TO THE PERSON WHO FIGURED THIS OUT AND FOR SHARING

I also faced the same problem. It is mere a date/time problem, killed me lot. Finally got the solution. This solution solves the problem.

THANK YOU.

All I can say Dave is OMG. What an easy fix. Can you believe something like changing the date could fix this issue? Unbelievable. I wouldn't have believed it if I didn't see it myself. I changed the year and BOOM all my heartache disappeared. Thanks a mill... and thanks for Google for finding you. Let's not forget KUDO's to the guy that figured this out and save us all. Thank-you.

Sincerely, Sincerely, Sincerely

Kim Knowles

Thank you, Thank you

My date was Jan 1st 2080... can you beleive that

Many Thanks

Hi Dave. Maybe you can help me with this problem. Whenever I try to go on a site that requires secure log-in, eg. bank, ebay etc. I get a security warning pop-up saying there is a problem with the sites security certificate. It says "the security certificate has expired or is not yet valid" and gives me options to continue yes/no or view certificate. I am operating Windows ME and IE 6, all updated and I also run AVG free anti-virus and spybot regularly. I have searched the web for answers to this and also asked several PPL including my bank's IT helpline. I have done everything suggested but still get the warning!

i have window 98 at business computer. now is saying invalid security certificate. how can i fix it

I agree with everything said over the years before me - please know that it STILL is helping people.

I haven't a clue why my laptop suddenly choose to go back to 1984 (!) - unless it's some kind of sci-fi conspiracy connected to the fact that it's 2010.

I would like to add however I enjoyed your classic, simple (and also) literary response.

In the 'Adventures of the Creeping Man' Sir Arthur Conan Doyle has Watson say, "If I irritated him by a certain methodical slowness in my mentality, that irritation served only to make his own flame-like intuitions and impressions flash up the more vividly and swiftly. Such was my humble role in our alliance."

I suppose even the best of us can be a little "Watsononian" once in a while....

Thanks Dave, add me to the list of grateful readers of your site - For some reason I was five and a half years in the past on my laptop??? How did that happen? Needless to say I can now get into aol once more, I was convinced I'd been hacked!!

thankz men u are so great...!!!

I've had this problem for a couple of weeks. I checked the clock and found it was set at 2001! Reset it to 2010 and, Bingo, fixed! Many thanks.

U ppl are the best. . Rhanks a lot . . no one could solve my problem. . Thanks a loooooooooottttttt. . god bless u . .

umm..I STILL NEED HELP !!

I can't get into my gmail.

My bios clock, and the windows 7 time and date are CORRECT.

is there a virus that would cause me to get a
"security certificate invalid" kind of response just for trying to get on gmail.com ???

i need help..there are a few CRUCIAL reasons why i need to get this fixed on get on gmail from my comp TONITE !

I'm thankful to you, DAVE. That's great solution. For a week, I've failed to sign in Yahoo to see may mails. Whenever I hit 'Sign in' warning pop up Security Certificate expired and not yet valid. Folloing your post, I corrected date/mont/year and computer a'clock. It works perfectly. Now I can sign in as usual. Great thanks to you.

Just worked for me, like a dream!! Stupid clicked 'OK' when i was mucking around with the date/looking into the past.... forgot to update it back to 2010 (!) ... thanks for the solution

HEY GUYS I JUST WANT TO CLARIFY FOR EVERYONE:

1: SECURITY CERTIFICATES ARE DEPENDED ON TIME ZONES

2: SERVERS ALL AROUND THE WORLD HAVE DIFFERENT TIME ZONES

3: SOMEONE CAN FIX THIS AND MAKE ALOT OF MONEY CALIBRATING SECURITY CERTIFICATES TO TIME ZONE PRIMARY KEY IN SERVERS AROUND THE WORLD, I DONT HAVE TIME

Everyone....hello....They are a few post on here that have not been answered....I see that most of the fixes have been done by updating your date on your PC...but there are a few people who's time and date are correct such as mine, and i still receive the error....when i look at my cert it has expired....and try and re-new it and it will not rene...any suggestions.

Wow, just yesterday I set my computer back 2 years because of a damned program and I forgot it instantly.
Thanks a million times!

hi.. its really a miracle although its a small problem to be solved.. actually today my pc been formatted n i forgot to set date n time.. hey its really a MIRACLE man.. thanx ... thanx a lot dave

I recently bought a PC with Win7. I could get on my company's websites, but yesterday I kept getting cert expired, both with IE7 and Firefox. I remembered that the PC just ran an update from Microsoft....lousy updates.
Checking can be disabled, but PLEASE re-enable after you go to your known website----it's for your protection.
In IE, go Tools, Internet OPtions, Advanced. Scroll down to security and uncheck "check for pub cert revocation", and uncheck "chk for server cert revocation."
In Firefox, its Tools, Options, Advanced, Encryption, Validation and uncheck "use online Cert........"
PLEASE turn them back on when finished. Hopefully Microsoft will fix it with another update.

OMG... you guys are amazing! I've been trying to figure this security thing out for such a long time! Thanks for all the help... my date was set back to 2003!!

OMG...I was just having the same problem with the security certificate and yeah my date was also set back to 2003!! What a quick and easy fix for a change THANK YOU!!!!

You are great man! Thank you so much! :)

For those whose Date/Time was not an issue:
Check your host file under C:\WINDOWS\system32\drivers\etc\host
Mine had all the google sites listed there and after deleting those it started working fine.

Thank you Utanko13....
I did exactly as you said and voila....Gmail webpage is now opening.....

This is Bull i have the same problem date is set right on PC in both Vista and in Bios. problem is on firefox and IE and an ftp style program. If I set the pc to the WRONG DATE ie yesterday everything is OK. Problem also replicates on an identical PC with different software installed ITS NOT THE DATE

I want to thankyou for the help i just google a questing and here is the answer thanks again

Thank you very much for the information... google has all the answers.

Thank you!!! Thank you!!!! Thank you!!!! I just came back from being away on vacation and have spent the last 24 hours scanning everything trying to find why I have this same problem. Found this article, checked my date and somehow it had re set to 2001--- how I don't know but re-set the date and everything is fine now. WHEWWWWW!!!!

Let me add my thanks. We had a power shutdown in Toronto yesterday and it probably is responsible for screwing up the time on my computer.
Scared the hell out of me this morning when I couldn't access my email because of expired certificates. Fortunately found your answer and found I had traveled to 2023. Thanks again

ingenious

I just fixed a similar problem with a client who claimed that the solutions here did not work for him.
He got the error every time he started Firefox (3.6.6) but did not get the error with IE 8. The date was good and both programs were up-to-date. He could still use Firefox after canceling the message. He used the "Plain Old Favorites" add-on in Firefox in order to access IE's favorites from within Firefox. The error referred to https://access1.sbc.com which is the secured AT&T site.
There, as plain as the nose in front of your face, is the clue, Dr. Watson. I started IE 8 and selected access1.sbc.com from the favorites. While it was displayed, I removed that favorite from the list and restarted Firefox. The error was gone. I put the favorite back in again through IE 8 and the error came back in Firefox. So, I copied the address from IE 8's address bar into Firefox.All of a sudden, Firefox came up with a screen to walk me through storing an updated certificate in Firefox. The problem is now gone.
This may not be the solution for you, but it is not difficult to test. Check your favorites and/or bookmarks for the website listed in the error message. If you find one, delete it then try to access the site directly.
Hope this helps someone.

Fantastic!

yea went through all the security settings. No joy.
"let's google it" said Natalie, my other half.

Lo and behold there's the answer.

Hi there, just like everyone else I have been dealing with this security issue for 2 days and I think it messed up my password getting into Face Book cause I tried to get in and it said it was wrong and I reset again and again til it took. also had to get new key for anti virus, I was trying to go into Paypal to update fund source and the message came up so after some dismay I finally did a search like you all did and checked the date and it was exactly 1 year ahead, I went back in time and poof fixed, I don't know how it happened but can't rule out my 4 year old playing games at Legos.com Thanx for your help!

that was great !! that security certificate expired is killin' me! changed my date and time and now its working.. thanks a lot..

thanks, dave.
don't know how it happened, but found i was living back in 2006.

gary again!
i don't know why, but yesterday and today when i turned on my computer, the date was still in 2006, and yes, i did click apply changes after changing date. anyone any ideas??

gary

thank you very much.
this simple solution does solved my huge problem.
:)

You are super cool, thank you SO MUCH for answering this question and posting the fix solution. I changed the date and it works! Thanks Dave Taylor!
All the best to you and your family,
Kris Kemp

Correcting the date on local machine fixed the issue.
Thasnks,

genius. Thank you so much. Wish all other postings on other sites just pointed here. So simple and so the answer.

I had the same problem. correcting the Date/Time it resolved the issue, Can some one tell it This s bug or someone tried to hack the computer

Damn Google is good. First site I got with this "getting certificate errors on most sites but nothing wrong with certificate" Date set to 2001 instead of 2010.

Thank you so much! Definitely been working on this for several weeks and then I decided to google a solution! Thank you

Nope, the date's perfectly fine, 10/4/10. I tried opening FB on google chrome, forefox & IE which i never use any more. Nothing worked & every time it said that there was a certificate error & a big red screen came up on chrome like DON'T DO IT lol. So what's next?

I've been receiving the invalid security certificate warning whenever I was about to open my emails but I just closed the dialogue box and ignored it. But, it was not until yesterday when I was about to open my email and coudn't make it due to the problem. I got confused. I tried to find the information about how to fix it and I FOUND YOU. I checked my time and date setting and OMG, it was set for 8 years in the past. THANK YOU very much for the SIMPLE and EFFECTIVE solution.

On one of the games I like to play there comes an "error loading bitmap Data/graphics/title/snapshots/lady_pic_-36553975.png ? What in the world does that mean? Can it be fixed somehow? Hope you can help. Thanks.

Thank you, I too had this error, then i noticed that the date and time were incorrect, so I corrected and everything is working fine.

I was having the same problem of secuity certificate error. Fixed the date and its gone.
Thank You

Elemental my dear watson ! HAHAHA wrong date here too...

FOR ALL HAVING THIS PROBLEM, CHECK INTERNAL BATTERY VOLTAGE (USUALLY 3 VOLTS, BATT TYPE: CR2032 OR SIMILAR) SOMETIMES A SMALL RECHARGABLE BATT IS USED ONLY TO KEEP CLOCK/DATE GOING WHEN YOU TURN OFF THE MACHINE.

OF COURSE WHEN THE VOLTAGE IS LOW... CLOCK AND DATE RESET TO MANUFACTURE DATE/TIME AND YOU BECOME TO GET CRAZY WITH "INVALID CERTIFICATE MESSAGES" AND MANY OTHER DATE RELATED.

THIS ALSO COULD BE CAUSED BY A LINE VOLTAGE FLUCTUATION (BROWNOUT, PEAK, ETC) AND BATT A LITTLE BIT LOW.

THANKS TO ALL !!!

Sshhhh, I struggled with this problem most of the day today and was preparing to go all command line on it's ass...boy is my face red.

THANKS. haha, had changed my date by mistake.

I had the problem after my wife moved my computer and unplugged it, So, the battery is probably shot.
I also wanted to warn others in the area in which I live; when you set your time zone I have had problems with the choice "Indiana Eastern". I set it for Eastern United States and checked the box for "adjust for daylight savings." Hopefully that will cure the problems I've had with the expired certificates and the time changing by itself. Who know's it's Microsoft.

Thank you Dave my problem is resolve,i am delighted

Thank you!! An info site that actually helped! it was indeed the date/time thingy, PC reset itself after a powercut. You've saved me a good deal of teeth gritting and swearing.

Many, many thanks. Have been trying and trying to find a solution to the "expired security certificate" message I kept encountering. After searching for help on Google I found your website and, hey presto, the date/time solution worked.
FAB - U - LOUS!!!! Can now continue to order Christmas presents from Amazon!

Many thanks, Val of Worksop, Nottinghamshire, England

Dave

Thanks a zillion for fixing this up for me.Been pestered for almost 2 weeks now and ended up blasting Dell (for the faulty OS) and Microsoft (for faulty IE).Jesus Mary Joseph ! it din't even strike me it could also be such a small issue.

Cheers

This is just great! I tried so many options, uninstall, install all of the above: firefox, IE,Safari,Google chrome...Went thru all preferences, security option,failed , failed failed, failed! ....it was just that the freaking date was wrong!That is it....as simple as it is!it is working now!
Thanks!

Worked for me too - thanks Dave!

Oh, Thanks to your bloggers I got the solution to the expire question. My date of my computer was also wrong. Thanks you so much.

Thank U for the answer.. In my system it was showing as 2030. When I changed back to 2011..everything became normal....

Just wanted to add one more "Thank You" to the list. This issue was making me crazy!

well thanks a lot forthe inf , i did everything but nothing jsut a simple date changing can makes a difference ,'once again thanks a lot

I found it.

For windows do it: first put windows CD/DVD into DVDRom and then go to ... Start > cmd (administrator) > sfc /scannow
and then reboot

this commend fix missing DLL file. sfc (System File Checker)

THanks guys! I had changed the date for next month andn hence my VPN got logged off and I was not able to re-connect. Read this resolution and suddenly remembered that I had changed my machine's date. Set the date right and I am back on work.

Thanks....

Oh Dave! We just got 2 refurbished Dells; the first one worked great. The second one arrived also UPS but 'invalid security certs' kept popping up so I couldn't read my email, check my bank, pay my mortgage and other bills, etc. I mean, really IMPORTANTE stuff. I read this article, checked the pc date, and sho'nuff, it was set to Feb 23, 2006! I fixed it and no more problem-o. I am SO-O-O grateful. All week we've been tortured and chagrined trying to deal w this. I wish I'd clicked on you first to fix it in like 5 seconds!

wow thank you so much! i work as a IT tech and cant believe i missed that! jeeze im dumb haha! well at least ill never make the mistake again. looks like this helped a lot of people, well thanks again!

thank u so much... it worked for me too:)

@ Abhinav - maybe it was the future you who changed the date.

OMG. Thankyou so much, I downloaded a dodgy program a day before this started happening and thought i had a virus.. I had just formatted and reinstalled for that exact reason. Even my 2 IT support employed siblings said I was infected. I ran hundreds of virus scans, then found yoou! Thanks so much! <3 My date was set back in 2002.. so yeah!

OMG!! THANK YOUSO MUCH.. IT WORKS :)

ThankYou :)....This problem troubled me for long.

worked for me :) .
thanks a lot!

Just today I started having this same problem and it was making me crazy... turns out I accidentally changed the date yesterday. THANK YOU!!

Thank's for reminding me to keep my mind open. Such a simple solution but as humans we always look for the coplex solution. THANK YOU

Sir,

my Hotmail certificate expire i have want new ssl file continue phasing problem !!

kekekekek oooooooohhhh yeeeaaaaah .
after suffuring beeing unable to enter the gmail and hotmail, I discover that the date in my PC is 12 years older the current . OMG Because I have changed my new screen card.

you are the grate man dave.............i thought you are kidding me but it,s worked

Thank you!! My parents had the same issue, where the security screen was popping up on every page of banking site. This solved the problem!

Who knew? Thanks so much, this solved my problem. I was checking a date on the calendar today and forgot to set it back to today.

I to have a problems with security certificates. Unlike all the thankful people above my time and date is correct. l have tried the few tips above and nothing works. This problem started after downloading explorer 8. Any help would be appreciated

Thank you! I just stumbled across the solution, but didn't realize it until I saw your postings here! I had security-certificate warnings popping up on all sorts of sites. And, I noticed my date/time/year had changed. I fixed the date/time, but then went googling for the solution to the security-cert problem, found this site and realized I had already, unbeknownst to me, fixed it!! It's working fine, now! GREAT to find such an easy fix!

Nothing wrong with my dates. My "Trusted Root" and "Trusted Publisher" and "Trusted Intermediary" certs are all courtesy of Windows Update.

I can delete them as often as I like, or place them the expired in 1999 etc and "Fraudulent Microsoft" ones in the Untrusted store...but they'll all find their way back into my Trusted Root.

I actually think I know how and why. I'm pretty sure it involves something to do with the 40 or 50 "Run Without Permission" ActiveX add-ons in IE8 and 9. On my systems, all set by default to Approve every website in the world.

But keep celebrating your inability to see a permanent clock clicking over in the corners of your screens ;)

FANTASTIC. I WAS CHECKING FOR AGES AND THOUGHT MY YOUNG CHILD HAD DAMAGED MY COMPUTER. IT IS SIMPLY THE DATE WAS WRONG. THANKS SO MUCH

Nice dude..thanks for the solution...

thank you thanks a lot.. I got pissed off trying everything.. but it didnt worked.. thanks a lot mate.. DAVE.. god bless you.. :)

Thank You....

I was having the same issue, but my date and time were correct. Just for the heck of it, I tried changing the date (to a false date) and then changing it back (to the present) and it worked!

Fantastic advice!! I had the problem but only on my netbook and I struggled for hours, expecting to have to go to the computer shop to solve the problem. All working well now. Many thanks.

i had a problem with the certificates but i worked after changing the date thanks very much.

Thanks Very Much........

Thank you bro.

The server's security certificate is not yet valid!

the above problems facing, but my system is not connected (yahoo mail) please rectify the above problems.

HI DAVE, I`VE JUST BEEN READING THE COMMENTS ABOUT VARIOUS INVALID SECURITY CERTIFICATES..UP UNTIL A COUPLE OF MINUTES AGO I HAD THE SAME PROBLEM WITH AOL SIGN IN AND DID`NT THINK ABOUT TO SEE IF MY PC`S CLOCK WAS OUT OF ZINC...IT WAS AND NOW IT`S NOT SO THANKS FOR THAT..WHY MY CLOCK DECIDED TO GO CONTINENTAL AND 9 YEARS AGO IS A MYSTERY BUT IT`S FINE NOW SO THANKS AGAIN.

i wrote my certification exam since last and didnt download it until this year but when i tried using the certification id i was given i was told that it was invalid please i need an urgent attention regarding this situation on how best to salvage this situation because i need to download those certificates. PLEASE SUGGESTIONS WOULD BE GREATLY APPRECIATED ASAP.

OMG - this has been bugging me for a while now. I wondered why it said the cert wasn't valid till July. It turned out for what ever reason the date was had not updated - even though it was set to do so. Once I reset it (it thought it was June) all was fine. Since I don't show the date in the bar it never occurred to me it was wrong.

So, my gf had this problem and I found a solution to it online here. ....Dang Broads lol

Hey dave,Well on facebook i try to go on tinychat and it says "Not signed by a valid security certificate, and I Really Need My TinyChat report back ASAP

Thanks,Georgia<3

Thank you SO much! I couldn't figure out why all these messages were popping up telling me that the certificates were expired. (I got a good bit paranoid when I was logged into my Chase account and it happened!)I Googled "messages certificates expire" and clicked on this webpage. After I read it, I remembered that I'd checked the time and date a few days ago to see what day December 15th fell on. Apparently, I clicked the date and saved it. Thank you for saving me hours of time and worry. Much obliged! Kindest regards, Nan

Hi Dave -

My cousin's provider is Frontier. She is unable to get onto the web. Sometimes she gets a message that the security certificate is invalid. No one can seem to locate her problem. Even had a modem change. Can this security certificate thing keep her from getting onto the web? Thank you John S.

I got the security error 80200010 when updating. It said update failed. I tried again and it updated. Does that mean that error was resolved Dave or do I need to do something else to get rid of it? Thanks Dave,

YOU are undoubtedly one of the smartest people on this universe. Two of my friends, software engineers couldn't friggin tell HOW to get rid of it.
I don't know how to thank you, really.

Well, butter my butt and call me a biscuit. I had the SAME PROBLEM on my laptop, and saw that the date was January 1, 2001!

How it got this idea, I don't know: but thanks for keeping this post alive! I only wasted ten minutes on the problem. (All the rest of y'all have my deepest sympathies.)
