Gluetun, qBittorrent, and Port Forwarding, qBittorrent Not Seeing Forwarded Port?

[Peter-Nincompoop]

I have qBittorrent and Gluetun both running as containers and a wireguard VPN through ProtonVPN with port forwarding enabled. Everything seems to be working except qBittorrent still shows to be behind a firewall, so not sure what to do next. Any advice? Details below:

• The "Test Your Setup" step on the Gluetun wiki works (command below). I do have a concern with this one though - my wireguard config shows an endpoint IP of xxx.xxx.xx.x0x while the IP from the below command (and the IP in the ip file in the Gluetun container) show xxx.xxx.xx.x1x. (My docker-compose VPN_ENDPOINT_IP is set to xxx.xxx.xx.x0x
  docker run --rm --network=container:gluetun alpine:3.20 sh -c "apk add wget && wget -qO- https://ipinfo.io"

• The "Test It" section of the Gluetun port forwarding wiki works with the forwarded port I find in the forwarded_port file in the Gluetun container

wget -qO port-checker https://github.com/qdm12/port-checker/releases/download/v0.4.0/port-checker_0.4.0_linux_amd64
chmod +x port-checker
./port-checker --listening-address=":forwarded_port"

• qBittorrent shows to be connected to the correct city/country with the xxx.xxx.xx.x1x IP using the below command from within the qBittorrent container terminal:
  curl -sS https://ipinfo.io/json
