I will specify already that I am talking about two completely different networks in two different houses.

I have configured PiHole in a Raspberry Pi Zero W, running DietPi and installing PiHole directly from there. This is running smoothly in my apartment since day 1. I have there a TP Link AX10 (AX 1500).

Now, I wanted to install PiHole also in my family home. I am using a Raspberry Pi 4, running the latest Raspberry OS 64bit. The router here is a TPLink VX230v from my provider (it has no restrictions though).

Again here the setup was smooth and easy but it is just not working. I cannot resolve pi.hole domain locally, and I can’t see any query passing through the PiHole. I setup the DNS in the DHCP DNS settings as done previously. I also tried to install it natively without Docker, but same result.

It was so easy to setup the first time. What is happening here?

The only weird thing that I have noticed is that there is a third IPv6 DNS server in my DNS list on my network interface, that I have never set anywhere. Don’t know if this is normal honestly.
