Can you run it with LOG_LEVEL=debug? It would show how it's cleaning up after Wireguard fails.

However, I noticed the first time it tries to connect to Wireguard it directly fails with that particular line:

2023-12-02T10:21:03Z ERROR [vpn] adding IPv6 rule: adding rule ip rule 101: from all to all table 51820: file exists

Why is the ip rule existing on a fresh container? Or did you remove some logs before?

Today the error occured again on german location. Now seeing the debug.txt logs I think this is a selinux issue

$ sudo grep AVC /var/log/audit/audit.log | ausearch -i
type=AVC msg=audit(12/20/2023 15:47:27.644:166) : avc:  denied  { watch } for  pid=1909 comm=gluetun-entrypo path=/run/wireguard/tun0.sock dev="overlay" ino=5905581338 scontext=system_u:system_r:container_t:s0:c521,c664 tcontext=system_u:object_r:container_file_t:s0:c521,c664 tclass=sock_file permissive=0

Did you figure it out in the end? That's kind of strange file exists is the error if it's due to SELinux, I would expect rather a permission denied kind of error 🤔
Also happy new year!

Hi. I am getting the same error as @bl4ko.
I am running Fedora 40 with Glluetun to AirVPN.
I am running the container via Podman Rootfull Quadlet.
