Consistently Random DNS Failures

Debug log:

Experiencing very frequent DNS resolution errors.

Youre debug log shows that Pi-hole is working. However, your DHCP server (the router) is passing its own IP as the DNS server, and not the IP of Pi-hole. This may not be related to your problem, but it's not the correct response from the DHCP server if you want all your devices to use Pi-hole.

The DHCP discovery also shows a network connectivity issue. This may be related to your problem.

Just confirmed and my router (Google Wifi) is set to use the Pi-hole ( in its DNS settings. Any suggestions or caveats with regards to Google Wifi to be aware of?

If you run a new debug log and look at the DHCP section, is this the actual DNS that the router is providing to clients?

One thing that I noticed is that the DNS pool on the Google Wifi was and the static IP that I'd set on the Pihole was, which was outside the DNS pool. I have adjusted the static IP address to to see if that helps.
