After starting up the container. The web portion is not available external of the docker container.

Expected Behavior

Docker behavior starts as expected.

How have you tried to solve the problem?

When walking through the debugging step here, the following step seems to fail where the web UI is not accessible:

docker run --rm -it --cap-add=NET_ADMIN \
  -p 9091:9091 \
  -e LOCAL_NETWORK=192.168.0.0/16 \
  -e OPENVPN_PROVIDER=PIA \
  -e OPENVPN_CONFIG=france \
  -e OPENVPN_USERNAME=username \
  -e OPENVPN_PASSWORD=password \
  -e DISABLE_PORT_UPDATER=true \
  haugene/transmission-openvpn

This is regardless of changing to another port that's not in use.
