Bug: Internal auto-healing restarts VPN connection even if it's stopped using control server

[smolpaw]

Is this urgent?

No

Host OS

Ubuntu 22.04.4 LTS (Jammy Jellyfish)

CPU arch

x86_64

VPN service provider

ProtonVPN

What are you using to run the container

docker-compose

What is the version of Gluetun

Running version latest built on 2024-04-08T07:43:05.096Z (commit 7b4befc)

What's the problem 🤔

When the VPN is stopped using control server the internal auto-healing restarts the connection after few seconds. Since control server allows both stopping and starting the VPN I assumed the VPN will stay shut until I send another request to start again.

Is this the intended behavior ?

• do not ask for updates, be patient
• :+1: the issue to show your support instead of commenting @qdm12 usually checks issues at least once a week, if this is a new urgent bug, revert to an older tagged container image

No it's indeed a bug, since the healthcheck isn't aware of the VPN "Loop state", and only knows to trigger a restart of the loop when it fails the healthcheck. The ugly workaround for now is to more or less disable the healthcheck trying to reboot the VPN with HEALTH_VPN_DURATION_INITIAL=1000h for example. Not a solution for sure though.
