Haven't had an issue logging in here, but I have been getting certificate errors, and looks like one of our site certificates may have expired. I will try and look into it this weekend. Havent had time this week as I have been working double shift all week.
Just an update: The main site SSL certificate is up to date, but it appears some cert for the server expired in the backend. That cert is supposed to auto-renew on its own and have never had it expire before. Unfortunately I am unable to login to the backend admin panel at this time. Not sure why I can't get to it but that might be part of the reason the cert hasn't renewed. I have a ticket in with support to look into it but if they haven't responded by tomorrow I will call them directly and try to get it resolved.
So finally managed to get a new SSL certificate up on the site server, so the error should be gone for now. Let me know if you see it again
For those interested, it appears that our server runs on an old version of linux that is no longer supported, and cannot be upgraded either, so I will need to standup a new server in the near future, and then transfer everything over to it instead.
For now at least the new cert will give us a temporary stay of execution, but Ill need to get that new server setup within the next month or so.
