LG TV is Internet blocked: Emby App asks for premiere / lags when pressing play

[Utini 14]

My LG TV is blocked from accessing the internet but can community with my Emby server on LAN. The Emby server has internet access and a fully valid Emby premier license.

When I'm open the Emby app on the LG TV and try to hir "play" it quite often won't do anything. Like the button doesn't work.

Then after a few mins I get several times the same pop which asks me to get Emby premiere or wait 10 seconds to continue.

Seems like a bug?
