[DL6ER]

You are still using v5.25.1. Please update your Pi-hole.

We released FTL v5.25.2 two days ago. It fixes exactly what you are observing here: An invalid configuration

May 10 13:38:31 pietran pihole-FTL[9794]: dnsmasq: bad dhcp-range at line 17 of /etc/dnsmasq.d/02-pihole-dhcp.conf

causing the entire application to crash instead of properly terminating instead.

[averello]

Thank you for the fast response.
I have updated to the latest version and I still have the problem:

Pi-hole version is v5.18.2 (Latest: v5.18.2)
web version is v5.21 (Latest: v5.21)
FTL version is v5.25.2 (Latest: v5.25.2)

• URL: https://tricorder.pi-hole.net/Y31OdiQv/

[DL6ER]

As the warning says, you have selected an invalid DHCP range. This is expected to prevent FTL from starting.

[averello]

Is that range specified in /etc/dnsmasq.d/02-pihole-dhcp.conf or in the web interface?
The 02-pihole-dhcp.conf file does not exist on my filesystem.
Is it a generated file containing the web interface values?

[DL6ER]

Is it a generated file containing the web interface values?

Yes, changes on the web interface recreate this file with your settings. Disabling the DHCP server deletes it IIRC
