Pi-hole not blocking ads

Help
1

Hi, I'm trying to block ads on my entire home network, but it's showing every ad. I think I have correctly set the DNS settings on my router and online DNS checkers have confirmed that I am on cloudfare's DNS. I believe that this is where my error lies, but I'm not sure. Other users on this home network are absolutely not tech savvy, so that's why configuring each client is not an option for me

My ipconfig /all results from a client machine:

Ethernet adapter Ethernet 3:

Expected Behaviour:

Ads getting blocked

Actual Behaviour:

All ads getting through, even tough the web interface says it's blocking roughly 50% of queries (105 blocked)

Forgot to mention, on my router the Local DNS server is set as my Pi's ip address, while the DNSv4 server is set to 1.1.1.1/1.0.0.1

Hello, did this happenned randomly ? Because it's the same for me, everything was working and since the 5 days nothing is being blocked. On the server if i do ``nslookup ads.google.com```i get 0.0.0.0 as the ip address but on my wireguard clients i get the current ads ip.

No, I set it up and it was like this

What ad lists are you using?

Go to 'Group Management -> Adlists' in the PiHole web interface.

Which lists are 'enabled'?

7

All of them. It's saying that it's blocking ads, but it's just not, I see the same amount, even added a few custom lists and am now around 1.4 mil domains on my adlists

Are you using Chrome? It could be bypassing PiHole and using a different DNS service.

In Chrome, go to Settings -> Privacy and Security -> Security -> Use secure DNS. Is this enabled? If so, turn it off and see what happens.

You also mentioned wireguard clients - how are these configured? They could also be using different DNS providers.

Your client is still using your router at 192.168.178.1 as DNS server.
