The wg0 interface is already up. To restart it, run wg-quick down wg0 and then wg-quick up wg0 again. WireGuard is not running as a separate process listening on port 7456, so you won’t see anything for it with lsof. Try a command like ss -ptuna | grep 7456 instead. Or run wg show to get a pretty display from WireGuard itself.
11/7/2020 · Hello, I ran into an interesting issue where restarting a container caused wireguard to not come back up with the error wg-quick: ‘ wg0 ‘ already exists .
