What is the version of Gluetun

Running version latest built 2024-08-19T17:09:35.713Z (commit 3f13093)

What's the problem 🤔

The configured network interface is invalid. Interface: "tun0" error when the interface is set to tun0
next output is Trying to listen on the following list of IP addresses: "tun0:6881" so i guess its fine because it found the port
just wanted you to know that this error message is showing up just in case its an actual bug

I'm not sure, this is the first time I see this, and it's a qbittorrent log; I saw qbittorrent/qBittorrent#143 which gives the same error. When do you get this error logged? Is it when Gluetun boots? That would explain it, because the tun0 interface may not be setup already, since it can take a few seconds. If you launch qbittorrent after Gluetun has established the VPN connection, does it log that as well?

[peterweissbier]

Yeah it happens on container boot. I can't test right now when I run separately if it happens too. Can test on weekend.
