Wireguard-VPN does not work

Hi folks,

trying to establish a VPN-connection to a Wireguard-server with a GL-E750 which is connected to the internet via Wifi.

This is the log-result:

Any ideas why it does not work?

Thank ahead!

Hello,

It seems that it cannot connect to the server.

When you import the same VPN profile on your pc, can the pc connect to the VPN server and does the Internet work fine?
