Issue Jellyfin reverse proxy - transcode while not necessary

[Oyo95]

Describe the bug
Hello,

I just installed Jellyfin on my Synology 920+ (Docker, on macvlan), locally everything works fine on port 8096.

I wanted to create a reverse proxy to switch to HTTPS but I encountered some problems:
- If I go through the reverse proxy of the DSM, the video cuts out after a few minutes, the web socket cuts out for no reason. log reverseproxy dsm.txt

• If I go through a reverse proxy Nginx in docker (through on macvlan), It works for IOS and in web but not on Android.
  I have a problem with Jellyfin on Android and Android TV. I can't log into the apps.
  Error message: "Connection could not be established. Check the host name and your network connection. "

The certificate was generated via the DSM / certificate / Let's encrypt

My dockerfile :
jellyfin.yml.txt

macvlan created in Portainer:

My nginx.conf :
jellyfin_nginx.conf.txt

My setup on Jellyfin :

To Reproduce

1. Go to 'Jellyfin app on android or Android TV'
2. Click on 'Change server'
3. enter your URL HTTPS
4. Error : "Connection could not be established. Check the host name and your network connection. "

Hi,

problem solved, there was an error in the nginx conf file:

  ssl_certificate /etc/nginx/certificat/fullchain.pem; --> before, it was cert.pem
  ssl_certificate_key /etc/nginx/certificat/privkey.pem;
  ssl_trusted_certificate /etc/nginx/certificat/chain.pem;

But with Android TV (on NVIDIA Shield TV), I have an other issue. the video cuts out after a few minutes, the web socket cuts out for no reason (only for H265 codec video). it seems that it transcodes when there is no need.
With Exoplayer --> play with Transcodage without tone mappage --> Ok but transcodage not necessary
With LibVLC --> Play directly but the video cuts out after a few minutes

Locally (via the ip: 8096), the video plays to the end without any problem.

Is it normally ?

I could only reproduce this error with Android TV (by the Nvidia Shield TV or Xgimi HALO)

Here the log file to reverse proxy :
jelly_access.log
jelly_error.log

Here, le Jellyfin logs:
