DNS Resolution Failures on 5.2.4

Please follow the below template, it will help us to help you!

If you are Experiencing issues with a Pi-hole install that has non-standard elements (e.g you are using nginx instead of lighttpd, or there is some other aspect of your install that is customised) - please use the [Community Help] category.

Expected Behaviour:

DNS Resolution occurs quickly.

Actual Behaviour:

Getting unresolved DNS issues on all devices. Even for simple requests like Google or things definitely not a block list.

Debug Token:


BTW it wouldn't let me submit this because it said I couldn't submit more that 5 links as a new user. Realized this is stemming from your template. I had only provided 1 link via debug token.

Please provide some examples from your log at /var/log/pihole.log.

Your debug log indicates your router's DHCP server isn't distributing Pi-hole's, but rather its own IP address as local DNS server:

*** [ DIAGNOSING ]: Discovering active DHCP servers (takes 10 seconds)
   Scanning all your interfaces for DHCP servers
   * Received 548 bytes from eth0:
     DHCP options:
      Message type: DHCPOFFER (2)
      --- end of options --

Accordingly, Pi-hole doesn't seem to have received any DNS traffic so far:

That's my fault on the logs. I reconfigured the raspberry Pi based on other user suggestions on forums. However, because of the issues since upgrading, I can't really leave it as the DHCP source for long.

Does that mean you no longer observe the issue?

If you still do, please provide a debug token where Pi-hole is actually receiving DNS; and also please comply with jfb's request for log file samples for failing domain resolutions.

No it means that it doesnt work. So I can leave it as the DNS resource for the house very long I need to wait until the evening when no one is working.
