I have followed the guide on how to setup WireGuard VPN Client on my Archer BE230 using the Tether app, however, it seems to be stuck at "Connecting". I have tried using the config that I've provided to Tether from the WireGuard client on my laptop and it does seem to work (meaning the config is not the issue). I have tried accessing the IPs behind the VPN with an iPhone connected to the WiFi of the Archer but it doesn't seem to load them (meaning that this "Connecting" is real and it has not established connection). The iPhone did continue having regular stable connection to the web though (google.com was still accessible, even though VPN was stuck at "Connecting"). Now I have left only the TV as a whitelisted client.

Any suggestions on what might be the issue?
