unauthorized via proxy

[procheeseburger]

Information

I have the container working just fine via compose but I can only access the webUI via ip:8080 I can't seem to get it to work behind my proxy: qbit.domain.com. I get a white screen that says unauthorized.

Current setup

All of my containers run behind NGINX Proxy Manager and it works just fine. This one just seems to respond with unauthorized.

how did you start the container? (don't forget to use backticks for creating a proper code block)

version: "3.9"
services:
  alpine-qbittorrent-openvpn:
    container_name: qbit
    image: guillaumedsde/alpine-qbittorrent-openvpn
    networks:
      - proxy
    volumes:
      - "${FILE1}:/downloads"
      - "qbit2:/config"
      - "/etc/localtime:/etc/localtime:ro"
    environment:
      - OPENVPN_PROVIDER=${OPENVPN_PROVIDER}
      - OPENVPN_CONFIG=${OPENVPN_CONFIG}
      - OPENVPN_USERNAME=${OPENVPN_USERNAME}
      - OPENVPN_PASSWORD=${OPENVPN_PASSWORD}
      - PUID=${PUID}
      - PGID=${PGID}
      - LAN=192.168.0.0/16
      - TUN=/dev/net/tun
      - DNS=${DNS}
      - HEALTH_CHECK_HOST=google.com
    ports:
      - "8080:8080"
    cap_add:
      - NET_ADMIN

volumes:
  qbit2:
    external: true

networks:
  proxy:
    external: true

Attempted Fix(es)

There are similar issues, I've tried adjusted the qBittorrent.conf to match without success.

If I set the LAN to the subnet of my desktop.. I can reach the webui via the IP:8080. if I set the LAN to the IP of my proxy, I just see a white screen with Unauthorized.
