DNS leak with ProtonVPN

Hello!

I did follow this guide but i went with protonvpn. I did achive that i can access my lan with VPN and get ProtonVPN when i check https://ip.me/

Im running wireguard on my android and have a wireguard docker solution.

But when i ran an dnsleak test i see my wan IP adress. When i ran proton VPN app i get no leaks but cant access my LAN.

Any tips how i can fix the dns leak?
