After upgrading my server to 1.1.4.2757; my Xbox One S will no longer see the server as available. I have tried to re-link the app, rebooted the server and Xbox and still nothing. The Xbox is running the latest client version (1.7.10). I am able to see and access the server from PC, Phone, web and windows 10 apps, so I know the server is working.
Sorry, I just saw a similar thread in the discussion. I should have put this under that. I also found what is causing the client to fail. I have the server set to always encrypt. When I change that to never encrypt it works fine. So, it is not liking the secure connection for some reason.
