gmail invalid security certificate

  • Question
  • Updated 1 year ago
When I try to open www.gmail.com in firefox or ie7 I get same error message as follows: Secure Connection Failed
www.google.com uses an invalid security certificate.
The certificate will not be valid until 5/2/2008 1:02 PM.
(Error code: sec_error_expired_certificate)
* This could be a problem with the server's configuration, or it could be someone trying to impersonate the server.
* If you have connected to this server successfully in the past, the error may be temporary, and you can try again later. Or you can add an exception...
What does it mean?

Correct your system date

The security certificate has a validity date (as mentioned in the error), if your system time is ahead of that date, the browser shows the certificate as expired.

All you need to do is to correct the date and time in the windows clock from the system tray.

----------------------------------------

Cause
This happens mainly because we use the system tray clock/calendar to see a future date and when we are done, we click "OK" instead of "Cancel". This sets the system date to whatever we were looking at.

This is a usability problem, not your fault! Windows has conditioned us to click on "OK" when we are done with a task.

Long term solutions
Microsoft could handle this by having the user put the clock in edit mode before changing the date or time.
A lot of user's use it as a calendar + we don't change the date/time very often - so the editing functionality does not need to be so easy accessible.

In the meanwhile, browsers which release versions and patches more often than an operating system, could have the user check for the system date/time as a possible solution to this error.

Sam King Has Got it right on... sometimes if, like me, you have a laptop and you're traveling... your batt runs out and your system clock gets screwed. or sometimes you screw it without knowing.
Either way, if your System clock is saying it saaaay January 2010 and it October 2009, the Security Certificate is going to say 'Invalid'. Simply correct the date and refresh Gmail's page in you Browser.
BAAMMM! you should be money.

when the error code is expired_certificate then date / time is likely to be the issue. Other errors I've seen are Invalid CA and so the cause may have been the results of malware infection... use something like HiJackThis to fix it up.

I used malwarebites to remove 765 infections from a malware infectionand followed all the steps and still get the error. My clock and date are correct also. Is there an other place to set the clock and date?

If you've got an Invalid CA message then there's a possibility it could be that malware has put entries in to your windows hosts file. So when you think you're going to a google site it passes you through another site first.
quick check - Start up Notepad... then open C:\windows\system32\drivers\etc\hosts
Look to see what entries are in this file.

great answer man. Solved my problem. Malware was redirecting all google pages to 89.149.249.195. Removed all entries, now fine.
