So, today I updated my pihole installation, got an error during DNS resolution (I forgot to chenge the nameserver in resolv.conf after changing some router DNS settings), so I stopped the update. Result: the updater told me to uninstall and remove unnecessary dependencies using autoremove.

I did that (since pihole was broken, could not use the cli and web interface was unreachable), and then proceded to reinstall using the official script (method 3 on the pihole website, using wget and then launching the script).

Installation was fine, no problem.

After the installation the web interface was unreachable, and doing pihole status resulted in [✗] DNS service is NOT running so I rebooted the rasbpi.

After the reboot I logged in into the web interface and everything looked just fine. I went to add some local DNS and CNAME to access some local services running on the network, I added the local DNS entry, 1 CNAME, and as soon as the CNAME was registered, all subsequent CNAME gave me errors and checking pihole status resulted in the same error as before.

A reboot resulted in the same exact process being repeated.

I tried to look online, but couldn’t find any useful solution, help.

I’m not super knowledgable on the topic, so can someone please help me troubleshoot my problem?
