XBox One -> Plex Server -> TVHeadend - not playing any channel

Hi all,

i run a TVHeadend Server at SERVER1.
At SERVER2 i run latest Plex Server.
I’ve installed a channel Plugin to have TVHeadend live TV Channels available in Plex Server.

If i start a channel at my MacBook --> works!
If i start a channel at my iPhone --> works!

If i start a channel at the XBox One --> Error Message saying i should make sure that the device is connected to the network.

All devices (Plex, TVHeadend and XBox One) are connected to a wired Ethernet (1 GB).

Any idea what’s wrong there or where to start investigating whats going wrong?

Regards

BoxSon

Could you post some server logs with debug logs enabled in the server settings?
