Invalid certificate Firefox refuses to allow access

I had to use IE11 to gain access, because Firefox in their infinite wisdom has decided your site is blocked off, just because your certificate expired.



Your connection is not secure

The owner of forums.emulator-zone.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox may only connect to it securely. As a result, it is not possible to add an exception for this certificate.

forums.emulator-zone.com uses an invalid security certificate.

The certificate expired on Saturday, 20 October 2018, 10:59:59. The current time is 21 October 2018, 12:15 am.

Error code: SEC_ERROR_EXPIRED_CERTIFICATE

the same for me im using Opera.
Now im here because im use my second browser called Yandex i was add exception and im here.
IE11 never .

adding as exception in latest firefox and work too.

Yes I am aware of the problem, unfortunately **right now** all I can do is wait.

Thanks... at least you are aware of it. My firefox has no option to add an exception... so I must use IE11 to get here.

Sadly I have no direct control over the server or the domain in order to get a new certificate. Also, you may use Google Chrome, sure it will complain at first but it will let you add an exception.

I decided to Reset Firefox back to defaults, and the Add Exception button appeared.

still not fixed...

Yes I am aware. You need to use Google Chrome for now like I do.

im using latest opera its working.

The problem has been sorted, sorry for the delay.

Thanks for fixing, but looks like you have to go through it all again in 3 months time.

No Let's Encrypt uses short-term certificates, which are automatically renewed. Assuming nothing breaks (ahem), this "should" never happen again.

Ah, thanks for the info.

We'll see if it works out. :D
