Hello everyone,
I recently tried switching my docker torrent client setup from haugene/transmission-openvpn to linuxserver/qbittorrent with gluetun for my VPN.
I have gluetun set up to use port forwarding with ProtonVPN which assigns a random port on every connection. Gluetun provides a VPN_PORT_FORWARDING_UP_COMMAND which can be used in this scenario to update the port used by qbittorrent. While I had issues with the example command in the gluetun wiki to do this, I eventually managed using a bash script I found in another forum.
My issue now is that my server shuts down for the night to reduce noise and after restarting, even though I have the container startup order set up, qbittorrent is no longer reachable on its webinterface. The logs do not indicate any issue though.
As far as I can tell, the stack as I have set it up is extremely finnicky in terms of startup order and time. If I start gluetun first and then wait too long before starting qbit, the port update script will fail because there is obviously no target for it. If qbit is up and running before gluetun is done, I typically can't access its webinterface for some reason and the network interface used by gluetun will set itself to loopback.
The result of this is that basically every morning I have to start and restart the containers in the stack a couple of times until I can access the interface and ensure that the port and network interface of qbit are configured correctly.
If anyone has a similar setup working that they could share or maybe another solution to my current issue that would be great. Thanks.
This is my docker-compose stack for the new setup
version: '3'
services:
gluetun:
image: qmcgaw/gluetun
container_name: gluetun
restart: unless-stopped
cap_add:

depends_on:

# condition: service_healthy
# restart: true

# ports:
# - 8080:8080
# - 6881:6881
# - 6881:6881/udp
restart: unless-stopped
And this is the script I use for updating the qbittorrent ports
#!/bin/sh
# update-port.sh
port="$1"
retries="${UPDATE_PORT_RETRIES:-5}"
interval="${UPDATE_PORT_RETRY_INTERVAL:-10}"
echo "Attempting to update qBittorrent port to $port..."
for i in $(seq 1 "$retries"); do
response=$(wget --quiet --save-cookies=/tmp/cookies.txt --keep-session-cookies \
--post-data="username=$QBIT_USERNAME&password=$QBIT_PASSWORD" \
--header="Referer: $QBIT_ADDRESS" \
"$QBIT_ADDRESS/api/v2/auth/login" -O -)
if [ "$response" = "Ok." ]; then
break
fi
echo "Login attempt $i/$retries failed. Retrying in $interval seconds..."
sleep "$interval"
done
set -e
if [ "$response" != "Ok." ]; then
echo "Unable to log in to qBittorrent."
rm -f /tmp/cookies.txt
exit 1
fi
wget --quiet --load-cookies=/tmp/cookies.txt \
--post-data="json={\"listen_port\": $port, \"current_network_interface\":\"$VPN_INTERFACE\", ,\"random_port\":false,\"upnp\":false}" \
"$QBIT_ADDRESS/api/v2/app/setPreferences" -O /dev/null
rm -f /tmp/cookies.txt
echo "qBittorrent port updated successfully to $port."
Update
After updating my stack based on the recommendation from hyphen612 it has been running flawlessly for a few days. This is my new docker-compose file. The extra script I used before for updating the port has been retired.

Update 2
The issue with qbittorrent not being reachable despite the container being healthy did not go away with the previous update. What finally fixed the issue for me was changing the tag of the container image.
I am now using the lscr.io/linuxserver/qbittorrent:libtorrentv1 image instead and that seems to work so far.
Hugged to death obviously
