I had this, I suspect you need to update the IP address of your Pi-Hole instance in the config to use the Docker network IP address. On my Pi-Hole instance, I have two IP addresses assigned to my Docker container - one for the external (i.e. 192.168.1.X) and one for the internal (i.e. 172.19.0.X) so that the container can talk to other containers on the internal network. I used the internal IP address on my config and it worked after.
