Can't get .m3u URL to play using chromecast

I’m trying to get a stream running on one of my chromecasts. Other URLs work, but this one for some reason not. It’s working in other players though.
Any idea how to change it to make it work? Below is how I configured it as a script.

Thanks,
TIm

play_n_joy:
  alias: Play N-Joy Radio
  sequence:
  - data:
      entity_id: media_player.living_room_speaker
      media_content_id: https://www.ndr.de/resources/metadaten/audio_ssl/m3u/n-joy.m3u
      media_content_type: music
    service: media_player.play_media

Any ideas? I got it to work with other streaming URLs but not with the URL of this radio station.

Thanks,
Tim

Did you manage to get this working?
