I had Pihole installed and running yesterday, then today had some network issues. Resolved the network problem and back on line and FTL was not running. Tried several solutions found on the net to no avail. Finally, I uninstalled and reinstalled again, FTL still not running.
This is on A Debian Buster server.
Expected FTL to run
FTL not running
Looks like you have the wrong IP address configured.
*** [ DIAGNOSING ]: Networking
[✓] IPv4 address(es) bound to the br0 interface:

10.1.1.1/24 matches the IP found in /etc/pihole/setupVars.conf

Edit: Also apache2 is blocking lighttpd from running. You have to configured apache2 to handle the Pi-hole admin interface properly if that is what you want to use.

How do I have the wrong IP? My LAN is multi-homed with two IP on same subnet, both 10.1.1.1 and 10.1.1.253 respond to those addresses on my br0 interface.
My apache is setup to handle the admin interface and I can access the admin web UI at 10.1.1.1/admin.
My gateway is 47.152.1.1 and responds to ping, why the diagnosic doesn’t see it I don't know.
As I said everything looks fine from the web interface https://share.polymicro.net/1581627802.png
BTW, had same errors when it was working.
what does pihole status show?
are you able to ping out to the internet from your server and can clients ping it?
yes and yes
[pve]/root/src/...hole/automated install (581): pihole status
[✓] DNS service is running
[✓] Pi-hole blocking is Enabled
Do you have anything installed that could be preventing FTL from starting like anything that relies on dnsmasq although FTL should disable dnsmasq when installed
No, as I said it was working, now it doesn't, even after a reinstall.
Does pihole -v display FTL as installed?
[pve]/root/src/...hole/automated install (584): pihole -v
Pi-hole version is v4.3.2 (Latest: v4.3.2)
AdminLTE version is v4.3.2 (Latest: v4.3.2)
FTL version is v4.3.1 (Latest: v4.3.1)
What does systemctl status pihole-FTL.service show?

That was it, killed the dnsmasq and restarted pinhole, now running
What was it? you had dnsmasq installed?
