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.

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tried everything so far but everytime I log into my email, it brings up the "this websites security certificate has been revoked" error.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!

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?

Dave,
Your buddy with the security certificate problem who figured out his computer date was wrong is a genius!! I had the same problem (though mine was a year in the future) and now, having changed it back, everything works very well. Many thanks to you both!

thank u dave thank u so much..............i read dis page and i corrected my date n time
and prob is solved now thank god........
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!

my power went out and had all kinds of problems. always set your date and time. that was my problem. thanks for the help.

thank you soooo muuucchh for the info! ive been searching far and wide why im getting this info!!

Hello,
Just got this problem yesterday was trying other peoples fixes, nothing worked, yours did thanks not sure how I changed the date but you are the man.
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.
