  • I cannot seem to find a way to create an exception and suppress dialog warning me that the
    website I'm visiting has a non-valid certificate (self-issued) AND that server's URL doesn't match the website URL (which is fine, since we're using server gateway).
    When loading the page browser shows me the warning dialog, and after I accept the exception it reports that "Server's certificate does not match the URL.This page contains some insecure content."

    Can you write me the procedure how to create a permanent exception so it doesn't warn me each time I restart the browser?

  • You can change opera://flags/#remember-cert-error-decisions to a higher value.

    Or you create your own CA cert, sign the server cert and add the CA certificate to your OS certificate chain. See

  • Cool, setting remember-cert-error-decisions just did the trick.
