Pihole suddenly stopped blocking ads

Help
1

Hi everyone,

Here's a gist of my setup:

  • I am running Pihole and Unbound together through docker-compose.
  • All of this used to work properly until yesterday.

What's happening right now:

  • Pihole is working fine and it says ad-blocking is enabled.
root@4a75d618cd43:/var/log# pihole status
  [✓] FTL is listening on port 53
     [✓] UDP (IPv4)
     [✓] TCP (IPv4)
     [✓] UDP (IPv6)
     [✓] TCP (IPv6)

  [✓] Pi-hole blocking is enabled
  • When I go to settings -> "search adlists", I see google-analytics.com multiple times. (I am using google-analytics.com as an example and this test proves that my adlists have the said domain.)
Match found in https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts:

  • When I do a dig google-analytics.com 192.168.1.xyz or dnslookup google-analytics.com 192.168.1.xyz:53 or dnslookup google-analytics.com 192.168.1.xyz, the DNS request successfully hits Pihole but it does NOT block it. Here is the log:
Nov 30 18:20:24 dnsmasq[1026]: query[A] google-analytics.com from 192.168.1.3
Nov 30 18:20:24 dnsmasq[1026]: forwarded google-analytics.com to 10.10.10.3
Nov 30 18:20:24 dnsmasq[1026]: validation result is INSECURE
Nov 30 18:20:24 dnsmasq[1026]: reply google-analytics.com is 172.217.14.196

So, my question is: why is Pihole letting the request through even though the domain is present in the ad-lists? And all of this used to work until yesterday!

Already tried but didn't help:

  • Restarting containers, throwing/re-creating containers throwing/re-creating the docker volumes. Nothing has worked so far.
  • Disabling IPv6 on my router.

Appreciate any help I can get on the matter.

Domains, not URL's.

Run from within your Pi-hole container, what's the output of:

echo ">stats >quit" | nc localhost 4711
