I cannot log onto common websites like mozilla.org , google.com , facebook.com etc. I get an error message saying the "certifcate is not trusted because the user is unknown" i corrected the date and time on my pc and tried the "delete cert8.db file." method can someone suggest anything else to solve the problem. I have ran full pc virus checks and network checks with avast, the only way i can access these sites is with the use of a linux usb boot drive, but with windows it wont let me.

hello, a possible solution depends on different factors:

  • what is the error code shown under technical details on the error page on your windows pc?

in case the error code equals sec_error_unknown_issuer, please attempt to add an exception on the bottom of the error page & inspect the certificate (see the screenshot attached for instructions):

  • which issuer information does the certificate contain?

thank you!

"This Connection is Untrusted" error message appears - What to do

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