DNLA Player issues

[Cerise]

Hello,

I have Jellyfin server running in a docker container on Synology NAS.
Here is my docker compose file (I think I could drop the ports section since in host mode):

Code:

version: '3.5'
services:
  jellyfin:
    image: jellyfin/jellyfin:latest
    container_name: jellyfin
    network_mode: 'host'
    environment:
      - PUID=1029 #user jellyfin
      - PGID=65541 #group docker
      - TZ='Europe/Paris'
      - JELLYFIN_PublishedServerUrl=192.168.1.253
    ports:                                                                                                                                                                                                                                                     
      - 8096:8096
      - 1900:1900
    volumes:
      - /volume1/docker/jellyfin/config:/config:rw
      - /volume1/docker/jellyfin/cache:/cache:rw
      - /volume1/media/videos:/media:ro
    restart: 'unless-stopped'
    devices:                                                                                                                                                                                                                                                   
      - /dev/dri/renderD128:/dev/dri/renderD128
     

I have a DNLA Bluray player (sony) connected on my home network (same as NAS).
Unfortunatly, I can't see the Jellyfin server whenever attempting to reach it from player.
I have already tried Plex server, I can it. But doesn't work with Jellyfin.

Does anyone has some idea ?
Thanks a lot
