Can't access Jellyfin over my https reverse proxy domain on anything other than PC

[GOffrier]

Hello, i'd like some help with that issue that's been bothering me, i was never able to use jellyfin over my SWAG reverse proxy while everything else works, i'm in docker and am using the defaults for both SWAG and Jellyfin, got nothing in logs and it works fine while accessing from my public IP. Below is my docker composes and the Jellyfin subdomain config:

Code:

version: '3.5'
services:
  jellyfin:
    image: jellyfin/jellyfin
    container_name: jellyfin
    user: 1000:1000
    network_mode: 'host'
    group_add:
      - "106"
    volumes:
      - /mnt/tank/Share/Apps/Jellyfin/config:/config

    # Optional - alternative address used for autodiscovery
    environment:
      - JELLYFIN_PublishedServerUrl=https://jellyfin.chungusnas.duckdns.org
    # Optional - may be necessary for docker healthcheck to pass if running in host network mode
