Pihole DHCP won't give ip to devices on home network

[grosJambon33000]

Expected Behaviour:

Pihole dhcp should give ip to all my devices on my network within the range i've defined in the GUI

Actual Behaviour:

I have a home server running debian 11. I'm not using any firewall of some sort (UFW...)

I've disabled DHCP on the router of my ISP (as i've got the option to do so, but not the option to change DNS )

Then after that i've enabled DHCP server on my pihole. and then no connection on all my devices.
I have to static an ip on each device that i need to get connected to internet.

if i put back my devices on DHCP mode, then no more internet connection as pihole doesn't give any ip to them.

my ISP router is 192.168..1
my pihole is 192.168..2
the range on pihole dhcp is from 192.168.*.3 to *.100

Tell me if you need more information about my network configuration.

Debug Token:

Here is the debug token

thanks a lot for your help as i'm fighting with pihole DHCP for about a week now...

There are a couple of issues with your installation. /etc/pihole/setupVars.conf contains two interface lines, /etc/dnsmasq.d/ does not exist, and (maybe as a consequnce your DNS/DHCP server is not working.

What kind of environment are you running Pi-hole in? Is this a docker installation? Maybe it's time to start fresh. But you could give the repair a try first.... pihole -r
