Good fellows, for those of you who have problems with the GW and the Wireguard Update: our gw had problems with the handshake:
The error was caused by an incorrect configuration of the ufw firewall:
we had port 51822 open but in tcp, not in udp. By modifying this the GW worked correctly and got panda peanut. Hopefully this will help others if the same thing has happened to you.
Greetings from the NSO Squad
