GL-MT1300 - USB Tethering issue with Huawei Mate 20

Hi,

If I use the phone for internet using USB tethering, the internet works, but the Wireguard client from the GL-MT1300 can not connect to my remote server.

If I connect to the same phone using WIFI tethering, the Wireguard client does connect to the server.

Has anyone experienced anything similar, could it be to do with the USB tethering driver?

I’d prefer to use USB tethering to ensure I’m getting the maximum speed possible. I know in ideal conditions it would not be much faster than wifi tethering, but I’d like to get it to work anyway.
