Ok, also perform the same test for Autodiscovery.
What address was configured for your domain to use RPC over HTTPS?
It may be that someone has changed your DNS records and that the name now resolves to another IP Address.

I just tested alanhardisty's recommendation and it looks like the issue was with the RPC virtual Directory in IIS. Integrated authentication was not enabled. It really did somehow change.
I will test a little more and confirm fix shortly.

No problems - it's a common issue but an easy fix.
