Chromecast HEVC playback issues

[Mathijs]

So I have ditched Plex lifetime for Jellyfin and I am really happy with it. I do have one small issue that I can't seem to resolve myself.

When trying to play high quality content (HEVC HDR 2160p) my Chromecast doesn't want to play this. Transcoding works fine for most other media, and I can play this specific media on my PC and phone just fine.

Chromecast is an older model (2nd generation). After starting playback the screen stays black.

Here are the logs and the details of the media I am trying to play:
