SOLVED: DirectPlayError when behind reverse proxy webOS

[andreafontana]

Hi,

I'm having issues with my reverse proxy configuration. I have both Jellyfin and Nginx Reverse Proxy installed as docker containers on a Zimaboard, and I'm trying to use the official webOS app as client. On local network everything's fine. Outside local network, I can access the web UI from the LG TV, yet I'm experiencing Playback errors. Specifically, whenever I reproduce a file from the beginning, direct play starts and no problem occurs. As soon as I skip forwards or backwards or continue watching an already started film, transcoding is triggered (even though the file is compatible with the client) and I get an error saying "There was an error starting direct playback". All the other clients I tried work fine, so it's related to the webOS app.

I tried using plain nginx, as well as cloudflare tunnels, same behaviour. I followed the official guides on how to set up npm (also commented the lines that are may cause problems with webOS).

I tried opening a port and accessing jf from WANIP:port and this problem does not occur. 

I'm attaching ffmpeg log and the errors I get with cloudflare tunnels.
  cloudflare tunnels error.txt (Size: 949 bytes / Downloads: 18)
  log.txt (Size: 60.3 KB / Downloads: 22)

Any ideas? 

Thank you,

Andrea
