Can't connect to server from ESP32 client #35

Open dwaynez opened 10 months ago

dwaynez commented 10 months ago

I am running Wireguard on a raspberry pi. I can connect with a number of devices (Windows, Android) and everything appears to be setup properly. I am trying to setup an ESP32 with a web server, but web server times out trying to load the web page. When I turn off wireguard I am able to access the webserver. Any advice?
