How to troubleshoot Pi-hole not blocking ads on some devices?

Hey guys..... :innocent:

I have been using Pi-hole for a while now and it works great on most of my devices. However, I have noticed that some ads are still getting through on specific devices (like my smartphone and one of my smart TVs).

Here is what I have tried so far:

  1. Confirmed that the devices are using Pi-hole as the DNS server.
  2. Checked the query log, and I can see the devices making requests, but the ads aren’t being blocked.
  3. Flushed the DNS cache on the devices and restarted them.

I also check this: Ads not being blocked using Pi-hole's DHCP. aws But I have not found any solution. Could anyone guide me about this? I am not sure if I am missing something in the configuration or if there’s a specific setting I need to enable. Could this be related to encrypted DNS (like DoH) or something else entirely?

Any tips on how to fix this would be much appreciated!

Thanks in advance! :blush:

Please upload a debug log and post just the token URL that is generated after the log is uploaded by running the following command from the Pi-hole host terminal:

pihole -d

or do it through the Web interface:
