Single dot domain/DNS root zone query issue with containerized wireguard

I got it fixed by binding the DNS listening port to the pihole node local address in the docker-compose file of Pi-hole,
in my case - "192.168.50.11:53:53/udp" instead of - "53:53/udp".

I reverted the solution because after making the change, the Pi-hole Docker container failed to restart automatically after a system reboot.

Issues when restarting image jacklul/pihole

This (Solve DNS Resolution in Other Containers when using Docker pihole) works but container failed to automatically restart on raspberry pi restart with this error in journalctl -u docker warning msg="Failed to allocate and map port 53-53: Error starting userland proxy: listen udp4 192.168.50.11:53: bind: cannot assign requested address" docker-compose: version: "3" # More info at https://github.com/pi-hole/docker-pi-hole/ and https://docs.pi-hole.net/ services: pihole: container_name…

At the moment, I have stopped using the WireGuard container, and everything appears to be functioning correctly.
