DHCP Server doesn't respond after update

Help
1

Since the latest update I installed (Core: 2.11 Web: 2.3) my DHCP server isn't running. The DHCP server's on all of my other networking equipment are down and this is the only running one on my network.

Every device (even devices that I know got an IP address before the update) fails to get an IP address.

Here are my settings, My network already uses the 192.168.1.xx range.

Try

sudo pihole -r

and chose Repair

If it is still not working afterwards, we need to have a look into your dnsmasq folder:

ls /etc/dnsmasq.d/

Pi-hole repair didn't work.
In the dnsmasq.d directory there is:

And in 01-pihole.conf there is:

Okay, there should be another file

root@ubuntu-512mb-fra1-01:/etc/.pihole# ls /etc/dnsmasq.d/
01-pihole.conf  02-pihole-dhcp.conf  README

Please check your /etc/pihole/setupVars.conf for the following settings:

DHCP_ACTIVE=true
DHCP_START=10.68.106.201
DHCP_END=10.68.106.251
DHCP_ROUTER=10.68.106.1
DHCP_LEASETIME=24
PIHOLE_DOMAIN=local

(that might of course be different for you)

If everything is fine, does clicking on "Save" (without changing any settings) on the Settings page in the DHCP dialog box fix the issue?

My /etc/pihole/setupVars.conf has all of the DHCP settings in there.
But that extra file (02-pihole-dhcp.conf) isn't in my /etc/dnsmasq.d... I also tried pressing save in the DHCP section of settings, that didn't help either.

Please try the following (all in one line):

source /etc/pihole/setupVars.conf; source /etc/.pihole/advanced/Scripts/webpage.sh; ProcessDHCPSettings

This was happening for me as well with this update.

I've filed it as a bug at Saving active dhcp config deletes /etc/dnsmasq.d/02-pihole-dhcp.conf · Issue #1080 · pi-hole/pi-hole · GitHub and included the fix as well.

That worked perfectly. Thank you very much.

Thanks, for some reason I haven't seen your issue. You are right, what I suggested above circumvents exactly that.
