Can not connect to server

I see that there are a few reports similar to this, but wanted to create a new ticket because I have dug out the error log. This is occurring on Windows Server 2012 R2. So it seems that it is getting outside any firewall since it is getting a 500 error code from the server.

System.Net.WebException: The remote server returned an error: (500) Internal Server Error.
