Hi, I have set up server 2016 with IIS Application Request Routing, (about 3 weeks ago) to enable sharing one internet connection for port 443, between a Remote Web Access server and an exchange 2013 server. The connection was working perfectly until this morning. Remote access on 443 fails to both servers. The setup was with different FQDNs and the appropriate certificates.
I cannot find any instructions to troubleshoot this type of setup there are articles on load balancing Exchange servers but nothing for this, I'm not even able to find out where the configuration can be accessed to see if something has changed.
