Emby Theatre for Windows can't connect to server

[spiller37 0]

When using the Windows desktop app I am not able to connect to a locally hosted server on the same subnet.  The server is still accessible from the same machine in a web browser.  I can't find a location for log files.  The location of the application is apparently locked behind a Microsoft Store datastore.  I really wish they would just release this as a normal windows application and not require the ridiculous MS store.

How can I troubleshoot this connectivity issue?
