Has anyone run into an issue in #WireGuard in which the Endpoint is a fully qualified domain name (e.g. vpn.example.org:51820) and the tunnel won't work, but it will work if you put in the IP address (which is IPv4)? I wonder if it has to do with having both IPv4 and IPv6 stacks running and active at the same time on the client and it can't, for some reason our another, establish the tunnel correctly?
