    Connection not Secure- Error Not Yet Valid Certificate


    Hy Guys
    I am pulling my hair out trying to fix this problem. I am getting this error for every website that I am trying to open right after the fresh install of Windows 10. I have seen and tested most of the fix but I am totally failing at finding the real problem here. I am using Mozilla and Edge browsers and its happening in both. Below fixes already tried;

    1- Time/Date of the System is Correct
    2- No antivirus is installed/Disabled Windows Defender as well
    3- Restarted router/connection
    4- Checked drivers/restarted PC
    5- Enabled and Disabled Firewall. Also checked the allow an app on secure/public network.
    6- Internet Options -> Lan Settings -> Checked Automatically detect settings


    I remember facing the same issue few months back on another office PC and after failing at fixing the issue, I just installed new windows. I will really appreciate help in this regard.

    Welcome to TenForums.

    Apparently....

    Even if the displayed time settings seem to be correct, you should make sure that the time zone settings of your system match your current location.
