Let’s see the reasons for such errors and what to do in such case.
The main reasons for such errors are:
- Your Computer’s date is set to a wrong value
- The Security Certificate has really expired
- The web-site is not trustable
Most common reason for such security certificate error is that the certificates are valid for a certain period of time, and if your computer’s date is set to other than the current date or correct date, there are high chances that you will get this warning. So the first thing to check when you receive such error is to check your computer’s date and time settings. If the date time keep re-setting again and again, then change the CMOS battery.
When you have set the date settings, you will most probably not see this error again. But if you see the Security Certificate error, then either the certificate of the website has really expired as it had to be renewed from time to time, or the site is not trustable.
TIP: Never ever put your important login id or password on such pages if you see the Security certificate error.
