WireGuard Sever with GL-AR750 not working

I made a wire-guard server with my GL-AR750 and just copied and the information to the wire guard program on my android phone but when I turn on the wire-guard vpn on my phone it shows connected with the Key Icon but I don’t get any data nothing transmits at all? any Clues?

I think there may be some problems.

The configuration you generated is a json format, which may only work on anther GL router now. If you want to use that in your phone, you may need to manually input those values. So that may caused the problems.

Should it be a dns problem? or configuration problem? Not sure.
