Do you only get this issue on Firefox?

It sounds kind of like an issue on the website administrator's end. If it works when you add www. to the website address, it looks like maybe the administrator either didn't include the non-www domain name in their SSL certificate or forget to configure the SSL certificate correctly for that domain name.

If the certificate is revoked then you won't be able to override it.

Can you post a link to a publicly accessible page (i.e. no authentication or signing on required)?

I tried Edge as well and it gets the same error.

This one works, but as soon as you try to register, the error comes up.

Thanks, guys, for trying to help. Maybe the site is really bad news and I shouldn't be trying to use it.

I get the same error that the certificate is revoked, so the website needs to fix this. .
