Chromecast with proxy

[s0129]

I am using Audiobookshelf behind Caddy reverse proxy and everything works fine apart from Chromecast. When I cast it connects to the chromecast but there is no audio. In the webbrowser it just spins saying loading.
I can't see any issues in the logs and have tried on multiple browsers and using Android app.

Any idea what I can try/test to debug this?
Do I need to tell Audiobookshelf about the proxy or something?

Can the device you are Chromecasting to reach the ABS server?

Yes both in the same subnet on same network.

Hmm, then no clue, sorry.
Is there anything in the Caddy logs?
Can you try to cast from a different device?

Also please make sure your server and app is updated

After more testing I found I can chromecast fine from Audiobook shelf to some chromecasts but not others. Pattern seems to be I can cast to devices which have a screen but not speakers. Might be these devices are newer? Any ideas?
