Port not opening and general unreliability

[Enduriel]

I currently have the following stack up and running:

version: "3"
services:
  gluetun:
    image: qmcgaw/gluetun
    container_name: gluetun
    network_mode: bridge
    cap_add:
      - NET_ADMIN
    ports:
      - 8888:8888/tcp # HTTP proxy
      - 8388:8388/tcp # Shadowsocks
      - 8388:8388/udp # Shadowsocks
      - 8000:8000/tcp # Built-in HTTP control server
        # other containers ports
      - 6881:6881     # qBittorrent
      - 6881:6881/udp # qBittorrent
      - 50000:8080     # qBittorrent
    volumes:
      - /data/local/gluetun/data:/gluetun
    environment:
      - VPN_SERVICE_PROVIDER=custom
      - VPN_TYPE=wireguard
      - VPN_ENDPOINT_IP=[removed]
      - VPN_ENDPOINT_PORT=51820
      - WIREGUARD_PUBLIC_KEY=[removed]
      - WIREGUARD_PRIVATE_KEY=[removed]
      - WIREGUARD_ADDRESSES=10.2.0.2/32
      # - FIREWALL_OUTBOUND_SUBNETS=192.168.1.0/24 I also tried this
      - TZ=Europe/London
      # - VPN_DNS_ADDRESS=${VPN_DNS_ADDRESS}
    restart: unless-stopped

  qbittorrent:
    container_name: qbittorrent
    image: cr.hotio.dev/hotio/qbittorrent
    environment:
      - PUID=1000
      - PGID=1000
      - UMASK=002
      - TZ=Europe/London
    network_mode: "service:gluetun"
    volumes:
      - /data/local/qbittorrent/config:/config
      - /data/external/badssd/torrents:/downloads
    restart: unless-stopped

  qbittorrent_natmap:
    container_name: qbittorrent_natmap
    image: ghcr.io/soxfor/qbittorrent-natmap:latest
    environment:
      - QBITTORRENT_SERVER=10.2.0.2
      - VPN_GATEWAY=10.2.0.1
      - QBITTORRENT_PORT=8080
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    network_mode: "service:gluetun"
    depends_on:
      gluetun:
        condition: service_healthy
      qbittorrent:
        condition: service_started
    restart: unless-stopped

Basically, everything seems to be working correctly, and the logs from qbittorrent-natmap suggest everything is going well:

$ docker logs qbittorrent_natmap

but the port isn't actually connectable when I check it on yougetsignal and my private tracker tests reports that it responds with connection refused. At one point it was reporting the port as open, but even then it completely refused to seed, and the private tracker stated that it was leeching and not seeding. I'm going to be honest I'm pretty new to the homelab thing so this is very much a learning process for me but this solution you set up seems like exactly what I was looking for and I hoped it would work perfectly but I can't seem to get it set up, I'm happy to try and debug this in any way, just let me know what you need. I have also tried the linuxserver qbittorrent with the same result.
