I can only make a wireguard docker if I add the line network_mode: bridge to docker-compose.yml
If I try to make a wireguard docker without that line I get an error:
wireguard | [FATAL] plugin/loop: Loop (127.0.0.1:50437 → :53) detected for zone “.”, see loop. Query: “HINFO 500036817.976505179.”
wireguard | Another service is using port 53, disabling CoreDNS
This means that a wireguard docker can only connect to an existing network (bridge) on which there are already portainer and yacht dockers and cannot connect it to its separate bridge network without errors.
I use docker-compose.
If I do not put network_mode: bridge to docker-compose.yml then wireguard docker create another bridge (i think that is wireguard_default bridge) but then I have this “loop” error.
I used your compose, using proper PUID/PGID since we don’t support using 0, and on x86_64 because i dont have an arm unit to test on and it worked… we might need the expert @aptalca to chime in, it’s very odd for sure.
what’s your docker-compose version and docker version? docker-compose -v && docker -v

With my yml wireguard is working and I can connect my android phone with NAS where is wireguard docker installed and I can connect all services on NAS but I can not connect to any other devices on my LAN
That is a config or host issue, let’s focus on the loop for this forum topic. For config support on wireguard (ie, reaching your full lan) discord is your best bet for quick resolution.
