When I was configuring my server I had the following set…
Settings, Server, Network “Secure Connections: Required”
Setting this to Preferred fixed my Server Unavailable Issue for the Xbox. Hope this helps others.
Full HTTPS support for the XB1 isn’t yet released (but we’re working on it!) - so ‘Required’ will not work with the XB1 app right now. Thanks for the reminder and advice!
