Invalid or Expired Security Certificate?

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!


Dave's Answer:

After thinking about this for a while, I wasn't sure that I had any particularly great solution to propose. My standard response would be to check the security preferences of the Web browser and to try visiting one or more of the sites using a different browser like Firefox.

In a private dialog, however, I was pleased to hear that the chap who sent in this question figured out the problem on his own, and it's a beauty:

Dave, just so you know, I've figured out my problem with the expired or not yet valid security certificates: the date on my computer was set wrong and it thought I was years in the past! Once I fixed the date and time, all of these problems vanished.

This is a simple solution to a vexing problem and, as Sherlock Holmes shared with his colleague Dr. Watson, once you eliminate all other possibilities, what's left, however improbable, must be the solution.

Indeed.

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

Tim said, on August 12, 2005 7:37 PM:

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

AK said, on November 29, 2005 6:32 AM:

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

Rhonda Heath said, on December 12, 2005 7:39 PM:

What if the date is not the problem?

Dj_Lord said, on December 13, 2005 8:39 PM:

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.

Robert Griffith said, on January 2, 2007 5:09 AM:

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

Lauren Dorman said, on January 6, 2007 5:44 PM:

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. =)

Bobby Lee said, on January 25, 2007 12:52 PM:

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!!!

nasir khan said, on February 16, 2007 10:14 AM:

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

jamie said, on March 15, 2007 11:20 PM:

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....

JoeSlovo said, on March 22, 2007 3:38 PM:

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.

edward said, on March 23, 2007 8:12 AM:

Mike said, on March 23, 2007 4:31 PM:

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

Abhinav said, on March 31, 2007 8:19 AM:

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

fung-lee said, on April 4, 2007 10:37 PM:

this problem is driving me NUTS!!

David said, on April 9, 2007 10:58 PM:

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?

firoj said, on April 17, 2007 12:08 AM:

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

Sue said, on April 24, 2007 2:37 PM:

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.

Debbie said, on May 3, 2007 6:23 PM:

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.

T.Dareez said, on June 5, 2007 1:00 AM:

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

bob said, on June 7, 2007 3:26 PM:

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

Ajinkya said, on July 5, 2007 3:40 AM:

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.

Everardo said, on July 15, 2007 8:39 AM:

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.

Bryan Murphy said, on August 18, 2007 5:25 AM:

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!

Adam Prall said, on September 22, 2007 7:14 PM:

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??

Mharjie said, on October 2, 2007 8:52 AM:

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!

Brian said, on October 3, 2007 7:00 AM:

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.

Mharjie said, on October 3, 2007 11:45 AM:

>>>

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..

dave tha slave said, on October 24, 2007 7:23 PM:

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

Maria Deruvo said, on November 6, 2007 8:30 AM:

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, ???

Rob said, on November 8, 2007 6:07 AM:

Khristie said, on December 13, 2007 12:02 AM:

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!!!

Sheryl said, on December 15, 2007 8:54 PM:

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!

cliffm said, on December 21, 2007 9:07 AM:

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!!!!!

Schweigenthaler said, on January 2, 2008 3:12 PM:

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?

Marlene said, on January 5, 2008 10:29 AM:

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.

SG said, on January 15, 2008 4:49 PM:

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

Lynn said, on January 19, 2008 10:15 AM:

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.

Mike said, on January 25, 2008 2:40 PM:

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.

Raelyn said, on January 31, 2008 6:12 PM:

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

Raelyn said, on January 31, 2008 7:20 PM:

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

naveen said, on February 26, 2008 11:54 PM:

Thank u sir,

CL said, on February 29, 2008 5:53 AM:

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.

Eddie said, on March 3, 2008 1:52 PM:

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

matt said, on March 4, 2008 6:06 PM:

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!!

Tahir Jamil said, on March 10, 2008 11:48 AM:

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

Julie said, on March 19, 2008 8:04 AM:

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!

Karen said, on March 25, 2008 12:55 PM:

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.

Waldorf said, on October 21, 2008 3:52 PM:

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.

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.

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!!!

Special K said, on February 1, 2009 5:37 PM:

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.

TAJ said, on February 3, 2009 10:31 AM:

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.

Scott said, on February 4, 2009 9:00 AM:

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

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

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!

Scott said, on March 10, 2009 9:53 AM:

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.

Erich said, on March 21, 2009 10:47 AM:

This was the problem! Thanks!

Kirkoe said, on March 25, 2009 9:39 AM:

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!

Vivian said, on May 21, 2009 9:00 AM:

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.

Sarah said, on May 21, 2009 10:08 AM:

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!

Judy Skelton said, on May 26, 2009 11:25 AM:

Sha said, on June 7, 2009 5:43 PM:

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?

Thomas Szeluga said, on June 9, 2009 4:40 PM:

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!

Ralph Bailey said, on June 23, 2009 1:41 PM:

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.

FriendlyFellow said, on June 23, 2009 6:56 PM:

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.

Jim said, on July 11, 2009 5:02 AM:

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.

stevo said, on July 24, 2009 10:14 PM:

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!

Rob Tolby said, on July 27, 2009 2:04 AM:

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

Ryan said, on August 23, 2009 5:04 AM:

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!

Sandi said, on August 30, 2009 9:48 PM:

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!

nancy said, on September 2, 2009 4:27 PM:

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.

Stuart said, on September 3, 2009 2:52 PM:

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!!!!

Dave Taylor said, on September 3, 2009 3:11 PM:

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.

kaushal said, on September 5, 2009 8:24 AM:

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

Mandy Bayles said, on September 7, 2009 3:51 PM:

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!

Dami said, on September 22, 2009 3:58 AM:

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!

dave whitehead said, on September 28, 2009 9:43 AM:

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. :)

Joe said, on October 19, 2009 8:36 PM:

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?!

Pintu Gupta said, on October 22, 2009 5:38 AM:

Dear Sir,

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

Pintu Gupta said, on October 22, 2009 5:41 AM:

Sir,

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

Dave Taylor said, on October 23, 2009 12:04 AM:

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.

Ann said, on October 27, 2009 10:26 AM:

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

Lee Like said, on October 29, 2009 2:02 PM:

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

Overlord (Damo) said, on November 2, 2009 9:59 PM:

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! :)

Andy said, on November 15, 2009 10:59 AM:

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!!!

Nellie, Mason, MI said, on November 18, 2009 2:55 PM:

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.

Susan Schlecht said, on November 21, 2009 12:56 PM:

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???

Anoop said, on December 2, 2009 8:23 PM:

Sonali said, on December 4, 2009 7:41 AM:

Thank You For Your Suggestions.

Kristina Tool said, on December 14, 2009 2:00 AM:

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.

Justin said, on January 6, 2010 2:04 PM:

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!

Shankar Iyer said, on January 8, 2010 11:33 PM:

"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.

magua said, on January 10, 2010 3:51 AM:

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

Skye said, on January 11, 2010 5:54 PM:

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!!

Artie said, on January 14, 2010 10:56 AM:

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

DeeAnna said, on January 14, 2010 6:02 PM:

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.

Aljon said, on January 24, 2010 7:14 PM:

anyway, thanks for the info..., you are the greatest...

Thanks for your information.

John said, on January 27, 2010 2:20 PM:

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

John said, on January 27, 2010 2:26 PM:

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.

Leslie said, on January 28, 2010 8:39 AM:

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

Bethany said, on January 28, 2010 9:36 PM:

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!

Amanullah durrani said, on February 4, 2010 11:24 PM:

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

Leslie Stompor said, on February 5, 2010 8:22 AM:

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!! :-)

May said, on February 7, 2010 3:55 PM:

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!

jim said, on February 14, 2010 11:36 AM:

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!

brijesh said, on February 14, 2010 10:17 PM:

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.

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.

Alice said, on March 10, 2010 2:25 PM:

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

Prabhu said, on March 18, 2010 9:44 PM:

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.

Kim Knowles said, on March 21, 2010 10:26 PM:

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

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

MadelineHere said, on April 2, 2010 10:21 AM:

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....

Graham Stone said, on April 3, 2010 11:57 PM:

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!!

Pham Truong Ky said, on April 22, 2010 2:08 AM:

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.

sam said, on April 27, 2010 11:07 AM:

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

Lucas Barr said, on April 27, 2010 6:06 PM:

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

Byron said, on May 1, 2010 3:03 PM:

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.

hhgygy said, on May 6, 2010 1:34 AM:

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

Martin said, on May 16, 2010 8:47 AM:

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.

Kaytee said, on May 19, 2010 6:50 PM:

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!!

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.

Amar said, on June 15, 2010 1:40 PM:

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!!!!

Tom McGuigan said, on July 6, 2010 6:11 AM:

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

amedissway said, on July 6, 2010 1:51 PM:

Ron Asselstine said, on July 9, 2010 12:20 PM:

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.

DogRomeo said, on October 4, 2010 4:28 AM:

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?

Muhadi said, on October 5, 2010 7:52 PM:

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.

A.J. Taylor said, on October 11, 2010 7:18 PM:

Luis Fer said, on November 7, 2010 1:20 PM:

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 !!!

Mark Schull said, on November 24, 2010 6:04 PM:

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.

Mark Lambert said, on June 30, 2011 7:30 PM:

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!

jonny said, on July 4, 2011 8:25 PM:

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 ;)

PLEASE SUGGESTIONS WOULD BE GREATLY APPRECIATED ASAP.

Catherine said, on September 5, 2011 12:26 AM:

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.

Nan said, on September 15, 2011 10:28 AM:

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 have saved articles in the "Favorite Section" but when I go to retrieve an article i get this comment every time "Article not found or expired on Yahoo News." Do you know why this is happening? Your help in getting this matter solved would be greatly appreciated.

All my websites became unavailable so I bought a new anti virus, spent a week trying to validate my windows cert and got NO _WHERE.

All I did to fix all those problems was put the correct date!!

Thank you so much, you saved me from going crazy!!

Ron said, on February 13, 2012 11:13 AM:

Try updating root certificates by going to:

Start > Control Panel > Add Remove Programs

Add/Remove Windows Components
Scroll all the way down.
Check Update Root Certificates.
Next, Finish, Reboot.

George said, on February 13, 2012 7:13 PM:

Ok this is what it seem to have cause the problem (IN MY CASE).

I used google docs on my android mobile phone.
For some reason my mobile told google that i was in NY, then in CA. And they idiots (google) have now block me out(certification got messed up) whatever. Again this is stupid. All because they trying to monitor users on everything they do, who they are, what browser they use, where they are coming from.

I logged out form my google mobile, and still dont work... The problem only occurs when i log into google docs from my phone.

Thank you so much. I was doing everything to solve the problem, looking for the certificate to get rid of the problem, thinking of formatting the system. But when I gone through your notes and changed the year from 2005 to 2012, that's works. That's really worked. Thank you my friend.

Sytse said, on March 28, 2012 2:02 PM:

I can give you 1 tip:
If you want your computer to be safe from malware and heuristic virusses DONT use AVG. That anti-virus doesnt recognise the newest malware/heuristics anymore unless you pay for an advanced version.
Besides that AVG slows down the computer like Norton does since the first 2012 update.
(use Avira or Kaspersky instead to be more satisfied ;))

I am SOOOOOO grateful for this post. We've been having issues with this for months and just kept 'continuing to website' unable to fix the problem. Hey presto, following this post we checked the date and discovered eldest son had changed date to make it christmas time in an online game so that santa would come and give him extra presents!!!! He got the extra present of a little talking to about messing with the family computer!!!!
Thanks!

Mellie said, on May 25, 2012 10:41 AM:

When I am logged into pinterest (there's an option to log in using your facebook account, but I do not use that option), I receive a pop up box: Safari can't verify the identity of the website "s-static.ak.facebook.com". It has the options: 1)Show cert 2) Cancel 3) Continue. I've tried all 3 but lately have been pressing "cancel" until I load the next page and it pops up again. I use an imac and I'm not even on facebook. Other times "Invalid URl" page comes up and I can't even get to the website at all. This happens with pinterest or facebook mostly. Do you know what it could be?

sandor g said, on May 26, 2012 9:59 AM:

Thanks for the great help. I had this problem for weeks on my desktop. I had to use my notebook for other sites. No where could I find any help until I read this. I did it and in 2 minutes it was resolved. I'm bookmarking this site for further use. Thanks again.

SERIOUSLY?

There are that many people out there who have f'ed up system dates on their computer and didn't know it?

Really? Do their calendars work? Don't they ever save a file and then go, hey I just saved it why is the date file stamp yesterday?

I don't believe it!

kiran kale said, on August 8, 2012 12:07 PM:

i too had the same problem. while reading each comment about successful solution of date correctness i checked my date each time which was correct. finally i checked my google chrome settings. there i checked "check for server certification revocation" which was at first place unchecked. this worked for me. hope if anybody find such problem which is not fixing even after correcting the time try this. it may work for u as well.

Carmela said, on September 10, 2012 11:40 AM:

This problem came up this weekend. Website security certificate. Went to Best Buys and talked to the Geek Squad. Sure enough they had a simple answer. Your computers date and time are off and does not match the certificate date. For me this worked. If it does not work you need to replace a battery in your computer. Cost at Best Buys about $4.00.

priyank said, on September 12, 2012 7:53 AM:

Malcolm L. Campbell said, on October 1, 2012 1:49 PM:

What if the time and date are right and you still get a message saying " This site has not been signed by a valid security certificate"?

Bob Cleary said, on October 8, 2012 2:44 PM:

Dave thanks for your help in fixing my security cdrtificate problem. I have another, my HP Photosmart 7510 printer, prints only the top half of the first page and spits out blank pages there after. I am running Windows Vista Home as my operating system.

I fix date and time of my computer, the problems of invalid certificate resolved

municipality said, on December 3, 2012 1:03 AM:

The site's security certificate has expired!
You attempted to reach mail.google.com, but the server presented an expired certificate. No information is available to indicate whether that certificate has been compromised since its expiration. This means Google Chrome cannot guarantee that you are communicating with mail.google.com and not an attacker. Your computer's clock is currently set to Thursday, March 30, 2073 11:25:05 AM. Does that look right? If not, you should correct the error and refresh this page.
You cannot proceed because the website operator has requested heightened security for this domain.

Kathie Givens said, on December 23, 2012 5:15 PM:

I have an old Certificate of Authenticity and software cd for Microsoft Works, and my new PC will not accept the Product Key!!!! so I can load Works. It's not a 2010 version, probably right before that date. Can I please use this? I purchased it with the old PC!

Thank you. Thank you. My wife was having trouble with this on her computer. I had the same problems, but several years ago and couldn't remember how to solve it. I look at the date and, sure enough, she had transported to the year 2099! Thank you Dave Taylor. I will save this site in my favorites!

Dave Cowan said, on March 13, 2013 5:18 PM:

I am thinking the date change thing is why I can't access iTunes for a new version or to download songs...but I purposely set my date back a year to avoid the crashing of a very expensive program I have that had a 'kill switch' program set to go off Jan 1 2013 (to force an upgrade). Any way around the 'invalid certficiate' issue?

Bill said, on March 15, 2013 11:53 AM:

Thanks so much.

Lewis said, on March 27, 2013 11:56 AM:

Several people have asked ... what if it's not the date/time?

John H said, on March 28, 2013 11:33 AM:

Some b****d changed the year on my computer from 2013 to 2813! Killed access to all secure sites and took me nearly all day to spot it

Probably going to be linked to a scareware scam so when you get a "Certificates out of date" message take the magnifying glass to the calendar date then run your virus checker.
