Replace this text with what is actually happening
I recently performed an uninstall and re-install of Pi-Hole with a static IP address. After setup and looking at the web interface, it said there is a DNS Server Failure. I logged in, checked the DNS settings are and didn't see anything I could tell is wrong. The status in the top left corner of the web interface still says there's a DNS Server Failure.

Debug Token:

Pi-hole is not running because there is another DNS server (connmand) using port 53:

[✗] udp:127.0.0.1:53 is in use by connmand

Resulting in a failure:

2025-05-17 22:19:44.037 EDT [2743M] CRIT: Error in dnsmasq configuration: failed to create listening socket for port 53: Address in use

You need to disable connmand and restart Pi-hole FTL.

If you disable connmand, you'll most likely break the network connection.

I performed the suggestion from deHakkelaar and it fixed the issue. Thank you!
