Gluetun wireguard very slow despite opened port

[Rootkittorrent 0]

Hello everyone,

Im reaching to you because I cant figure out how to make it work properly. I switched to AirVPN recently and now my download and upload speed seems to be unusualy slow when torrenting.
I have everything set up under docker with gluetun and qbittorrent with wireguard, I think I did everything correctly but despite my efforts I cant seem to get fast downloads, AND, I see some weird behavior :

When I restart the gluetun container, I get around 40MiB/s on qbittorrent which is very good imo, but after 10-20secondes it goes down again to 500Kbps or maximum 2-4MiB/s, it even goes down to 0B/s. Sometimes it spikes up to 8 but thats rare. I tried this on the ubuntu iso and cant figure out why it does that. I also tried to download the same torrent but on my windows PC with wireguard and the same config that I used under gluetun, and it worked flawlessly at around 40-50MiB/s without any spikes.

Here's a part of my config :

services:
  gluetun:
    image: qmcgaw/gluetun:latest
    container_name: gluetun

    cap_add:
      - NET_ADMIN

    devices:
      - /dev/net/tun:/dev/net/tun

    env_file:
      - .env

    environment:
      - VPN_SERVICE_PROVIDER=airvpn
      - VPN_TYPE=wireguard
      - WIREGUARD_PUBLIC_KEY=${WIREGUARD_PUBLIC_KEY}
      - WIREGUARD_PRIVATE_KEY=${WIREGUARD_PRIVATE_KEY}
      - WIREGUARD_PRESHARED_KEY=${WIREGUARD_PRESHARED_KEY}
      - WIREGUARD_ADDRESSES=${WIREGUARD_ADDRESSES}

      - SERVER_COUNTRIES=${SERVER_COUNTRIES}
      # - SERVER_REGIONS=${SERVER_REGIONS}
      # - SERVER_CITIES=${SERVER_CITIES}

      - FIREWALL_VPN_INPUT_PORTS=${AIRVPN_PORT_FORWARD}

      - TZ=${TZ}

    volumes:
      - ./config/gluetun:/gluetun

    ports:
      - ${WEBUI_PORT}:${WEBUI_PORT}
      - ${AIRVPN_PORT_FORWARD}:${AIRVPN_PORT_FORWARD}
      - ${AIRVPN_PORT_FORWARD}:${AIRVPN_PORT_FORWARD}/udp

    healthcheck:
      test: ping -c 1 1.1.1.1 || exit 1
      interval: 30s
      timeout: 10s
      retries: 5

    restart: unless-stopped

    networks:
      - media-net

  qbittorrent:
    image: lscr.io/linuxserver/qbittorrent:latest
    container_name: qbittorrent
    network_mode: "service:gluetun"
    depends_on:
      gluetun:
        condition: service_healthy

    env_file:
      - .env

    environment:
      - PUID=${PUID}
      - PGID=${PGID}
      - TZ=${TZ}

      - WEBUI_PORT=${WEBUI_PORT}
      - TORRENTING_PORT=${TORRENT_PORT}

    volumes:
      - ./config/qbittorrent:/config
      - /mnt/medias/torrents:/downloads
    restart: unless-stopped

I also opened the correct port on my client area and put the same port in the .env for the FIREWALL_VPN_INPUT_PORTS variable. When I test the port on the same client area it tells me that ipv4 is reachable and ipv6 not (thats normal because I deactivated it).

In SERVER_COUNTRIES I've set Switzerland, Nertherlands and Germany. The logs from Gluetun tells me its correctly connected and I get the connection status online on qbittorrent with the port being set up correctly too :



What am I missing ?
