Does this work for you? Pihole can't communicate with my Unbound container due to I assume port mapping issues, I've tried using different sets of ports and utilizing them in the DNS1 Entry, but no luck.

https://github.com/klutchell/unbound I believe you have to set 5053 in pihole DNS server setting.
