I have setup the single container and adjusted the bottom of pi-hole.conf in an effort to get Docker traffic to resolve.

For reference when I say Docker traffic I mean my DuckDNS unsuccessfully pings their server, I have to change the containers DNS to 1.1.1.1; Wireguard VPN set to use my PiHole once in network will not resolve any DNS (but I can access everything on the network as usual); even the adlists are failing to update from their sources but I can access them fine through my browser. Anything that shows up as Docker Host in Client (172.17.0.1) fails to resolve DNS. Below shows some of the pings when I VPN in from my phone to test. Even though it says a cached response it never successfully resolved on my phone.

Thanks for any help.
