Pi-hole and openvpn configuration

Hi all.
I have made the configuration of openvpn. I can connect from outside and access to my private network. I can navigate on internet too. The problem is that the pihole dns filter is not working. I have read some configuration guide on pihole site but is not working. After following them I can’t navigate anymore but still access to my network.
What’s your experience with that? Which guide you follow?
Thank you

HI,

Pihole isn’t support by OSMC, it installs packages which break Connman.

Thanks Tom.

Adguard Home works instead of Pihole
