I reported a bad certificate warning last year.

It's entirely possible that what your warning reports is correct:
The name on the certificate is invalid or doesn't match the name of the site.
Whether or not this causes other users problems every day, I don't know.
been getting this message when playing a 1 min game as in the picture:
"the identity of this web site or the integrity
of this connection cannot be verified"
it appears about 15 seconds left in the game and it freezes up my computer. i did a scan with malwarebytes and it found nothing
