Did you notice that you are unable to access quite a few webpages? Even Google’s gmail service produces this annoying error message on your browser?


This webpage is not available

The webpage at might be temporarily down or it may have moved permanently to a new web address.

Error 201 (net::ERR_CERT_DATE_INVALID): Unknown error.

Have you experienced problems updating your antivirus, problems connecting to your dropbox account, unable to synchronize your computer with the logmein and many other problems requiring internet connectivity while you are sure that your internet connection has no problems at all?

  • The solution is simple!

Just correct your computer’s date and time. This is the most common problem responsible for the above mentioned issues.

If your computer’s date and time resets each time you switch on your computer, it probably means that the battery installed on the computer’s motherboard is empty and you need to replace it.
