Bug: All containers connected to Gluetun stop working once Gluetun restarts/ or update via watchtower

Is this urgent?

Host OS

Synology Docker

CPU arch

None

VPN service provider

VPNUnlimited

What are you using to run the container

docker-compose

What is the version of Gluetun

v3.34.0

What's the problem 🤔

All containers connected to Gluetun stop working once Gluetun restarts/ or update via watchtower.

I had the containers separated at one point. Then combined them in one STACK

If I restart Gluetun then the connected containers stop working, when I manually restart the containers they work fine.

I removed the depends_on line as it still has issues after removal and the containers still work without this line as they are all in one docker compose yaml syntax.

I also removed gluten from watchtower updates for now until I can get this resolved.

Share your logs

Point me were to pull the logs if needed.
I believe this can be tested, container logs clear once I restart, which logs will be needed to troubleshoot this issue?
