SOLVED: Unnecessary transcoding

[hyunjuan]

Version：10.9.9
Client：Windows / Chrome
Server：Linux/Docker
Video File Format: HEVC 3840x2160 24fps 13777 kbit/s [V: hevc main L5.0, yuv420p, 3840x2160, 13777 kb/s]

When I play a video with a bitrate of 13.8Mbps through the Jellyfin WebUI behind a VPS reverse proxy, it force triggers the conversion to 1080p-10Mbps.
It shows “Reason for transcoding: The video's bitrate exceeds the limit.” On the same client, when I play it over LAN, it plays it directly without transcoding.

I'm pretty sure that the Jellyfin server/VPS server's network is enough to handle the direct playback of the video. I've left the Internet streaming bitrate limit blank or set it to 500 and it doesn't work.

Is there any way to turn off the bitrate limit. Or at least make it higher.

Thanks
