SOLVED: Chromecast with Google TV

[lkadin]

I can connect from my phone with the app as well as from my PC.
I can not connect from my TV with a Chromecast on it nor from my smart Google TV using the same app version.

I AM able to connect from the TV if I use a browser app.

I do not any revers proxy or anything set up.

What server version are you running?

[lkadin]

Jellyfin.Server 10.8.13.0 running on Raspberry Pi 4

You need to upgrade to 10.10. Version 0.18.X of the Android TV app requires server 10.10.X.
