Port 53 already in use and pihole-FTL offline

[Ckeuning]

Expected Behaviour:

I'm running pihole through docker-compose, I would like to run a dhcp server and from there connect the clients

Actual Behaviour:

When I start the dhcp service in the pi-hole settings I get an error:

I've checked the FTL service in the container and it's running:

The pihole diagnosis says this:

2024-04-16 14:32:23 DNSMASQ_CONFIG FTL failed to start due to failed to create listening socket for port 53: Address already in use

This is my composer script:

I've tried alot of things to solve this, a different src/dest port, trying to off dnsmasq which cannot be done anymore due to build in pihole v4.

Unfortunately no result

DNSMASQ_CONFIG FTL failed to start due to failed to create listening socket for port 53: Address already in use

You need to find out what other service is binding to port 53. What is the output of
sudo ss -tulpn sport = 53

It will be systemd-resolved causing the issue. Please see: GitHub - pi-hole/docker-pi-hole: Pi-hole in a docker container
