Hello!

I installed the wireguard server on my raspberry pi a few months ago and was really happy with it. I am using the android and windows client (on seperate tunnels).

Now, i haven't used it for a month or so, but now i went on a trip and needed to use it again. But for some reason, the windows client doesn't want to connect with the server. The client reports the status as "Active", but in the logs it's stuck at the "handshake initiation".

2020-03-28 00:54:22.820: [TUN] [abc.xyz] peer(E9N …/shk) - Sending handshake initiation

2020-03-28 00:54:22.849: [TUN] [abc.xyz] peer(E9N …/shk) - Awaiting keypair 2020-03-28 00:54:27.864: [TUN] [abc.xyz] peer(E9N …/shk) - Sending handshake initiation 2020-03-28 00:54:32.869: [TUN] [abc.xyz] peer(E9N …/shk) - Sending handshake initiation 2020-03-28 00:54:38.155: [TUN] [abc.xyz] peer(E9N …/shk) - Handshake did not complete after 5 seconds, retrying (try 2) 2020-03-28 00:54:38.155: [TUN] [abc.xyz] peer(E9N …/shk) - Sending handshake initiation 2020-03-28 00:54:43.333: [TUN] [abc.xyz] peer(E9N …/shk) - Handshake did not complete after 5 seconds, retrying (try 2) 2020-03-28 00:54:43.333: [TUN] [abc.xyz] peer(E9N …/shk) - Sending handshake initiation

However, i can't figure out what is going wrong. These are the things i've tried and noticed:

• I'm using a DynDNS Domain instead of the router's public IP. And the client does get the correct public IP (it shows it as the endpoint in the client)
• I've made sure that the wireguard port is open in windows and my router
• I can connect to wireguard from my phone with no problem. I can even import the tunnel of my laptop on my phone and use it.
• I cannot use the tunnel from my phone on my laptop, same problem.
• I can access my home network from outside on my pc (test webserver).
• I tried reinstalling wireguard

​

Is there anything else i've missed? Maybe a setting in windows?

Thanks for helping!
