I recently set up a PiVPN server on my home network, and created a No IP address because I have a dynamic IP. I set the WireGuard port as 33XXX and have no problem connecting on my phone or Ubuntu machine. Using the Windows client, the endpoint displayed with address is correct (e.g. properaddress.ddns.net:33XXX), but when I go to hit connect, it changes to list the correct IP, followed by a random high-number port. It fails to make a handshake, and keeps attempting on different ports (such as 45951, 10059), without a successful connection. I thought it might be a No IP issue, but the IP address itself is correct. I also thought it may be the WireGuard listening port, but WireGuard just appears to be trying to connect to the right IP on random ports according to the logs (with lines like: Sending handshake initiation to peer 1 (IP.IP.IP.IP:45951).

This only appears to be affecting Windows clients on two different machines, but working on iOS and Linux devices. Any fixes for this?
