T-Mobile

Moved to t-Mobile fiber which used CGNat, Have got access to Emby server from outside using DDns and tunnel. But the app will not connect using the same FQDN and port it says unable to reach server.

Known issue / limitation with T-Mobile - some addresses are unreachable by design.

Let me clear this up some. I can get to Emby using a browser by the FQDN. But not by the Emby app using the same FQDN.

How are you trying to do that? What exactly is happening?

[evanover 2]

Using a no-IP domain name and using the no-ip client with a tunnel set up. Can get to the server outside of local network using a browser. But when trying to use the android emby app it returns server unreachable.

Are you sure you're trying to connect using the correct address?

Using the same name and port for both the browser and the app.
