I am facing this issue in Linux, where I am using firefox and continuously getting this error:

ssl.gstatic.com:443 uses an invalid security certificate.

The certificate is not trusted because the issuer certificate has expired. The certificate will not be valid until 09/26/2017 07:10 AM.

(Error code: sec_error_expired_issuer_certificate)

Please assist me asap?

Hi, first of all, check if Firefox is up to date and remove obsolete modules. Do you have a google bar ou something like that?

You can check the date and time and time zone in the clock on your computer: (double) click the clock icon on the Windows Taskbar.
