Hi, my esp32 connect to the wg server, but it have no handshake and I can't do ping on it or see the web page trough wireguard clients, may you help me to understand why?

Hello, @raccococo! 👋🏻

First of all, monitor the behavior of the program from the Wireguard server side. Connection, incoming/outgoing traffic, time of the last handshake. Maybe ESP32 is disconnecting from the server for some reason. This data could shed light on a possible solution to the problem!

You should also consider that in my implementation of Wireguard, the server must necessarily use PSK to connect to the ESP32. And make sure that the PersistentKeepalive parameter is set to 15 on the server side. Otherwise there is a risk of packet loss and connection problems.

Thank you! I've changed the PersistentKeepalive but nothing changed, I also discovered that I wasn't using the external antenna because you have to change the position of a resistor. So my problem was the distance from the router in the end. Thanks anyway and have a good evening!

Oh, good! Glad to hear you solved your problem 😊
