I tried to set up wireguard using the "official" instructions which look pretty straightforward. Still, after completing them, there is nothing listening on port 51820, even though the port is open in the firewall and the wireguard interface is running. I basically copied and pasted the instructions to ensure I got everything right.
nc -zv [server address] 51820
nc: can't connect to remote host (xxxx): Connection refused
even though wg show says:
wg show interface: wg0 public key: XXXXX private key: (hidden) listening port: 51820
Does anyone have a suggestion what I could try? This is strange, isn't it?
