Cast / PlayOn nvidia shield

[jellyfin9r]

hello guys,

i recently found out it's possible to cast / playon media to other devices.
my setup is pretty simple, i'm running jellyfin on docker in my internal network.

1x Android (Google Pixel)
1x iOS
1x Android TV (nvidia shield)

I want to use my pixel and jellyfin app to cast / playon my nvidia shield.
But my nvidia shield is not listed as device to cast / playon.

Can you help me with my configuration?

Thanks in advance

What network mode is the Jellyfin container using? Host networking? Bridge networking?

Also why casting instead of the native Android TV app?

Thanks for your reply.

It's operating on bridge networking. We also use the native app which works great.
Sometimes we'd like to cast music from our smartphone directly to the shield.

How is the container setup? What ports are you publishing? Can you share your docker compose?

For testing, comment out the "ports" section and add "network_mode: host". Restart the container and try to cast.

changed the configuration and did a restart without success streaming to my nvidia shield.
i installed the dlna plugin, same outcome ... whats odd for me is that now i can cast from the iphone to my open session in a web browser.

Are there any essential configurations that may block the casting to nvidia shield?

Posting my observations from our matrix chat conversation.

I confirmed my recollection.

1) The app Jellyfin needs to be open on the Android TV.
2) Your user needs to be logged in or your user needs to configured to be able to control other user's devices.

tried with no success, also Port 7359 is not open
