intermittent slow page loads dns probe no internet

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

Expected Behaviour:

Web pages load promptly

Actual Behaviour:

Intermittently web pages will either load very slowly, only load after multiple refreshes or not load at all. When they do not load at all I get an error in Chrome along the lines of “DNS probe failed no internet”. When this intermittent behaviour occurs it affects all devices using the pi hole as DNS server and all web pages I try to access. If I switch to another VLAN that does not use pi-hole everything works fine.

From your debug log:

*** [ DIAGNOSING ]: Networking

   172.18.0.3/16 does not match the IP found in /etc/pihole/setupVars.conf

Thanks for your prompt response.

So the IP of the pi hole box is 192.168.1.111 so not sure what the 172.18.0.3 is referring to? I’m running this in Docker on Ubuntu so it looks like there is probably an issue with the docker configuration.
