Clients Connect, but no DNS resolution

Help
1

Expected Behaviour:

Upgraded existing Pi-Hole on Ubuntu to Ubuntu 22.04. Post-upgrade, everything should be back to normal.

Actual Behaviour:

Clients are receiving IP address, but not being added to Pi-Hole DNS records and cannot access internet. Pi-Hole can access internet. Log shows all Localhost queries, none from clients.

Debug Token:

https://tricorder.pi-hole.net/lvL5dxjo/

I'm not sure this is the issue, but your debug log shows a database error:

*** [ DIAGNOSING ]: Pi-hole FTL Query Database
-rw-rw-r-- 1 pihole pihole 2.3G Nov 28 20:13 /etc/pihole/pihole-FTL.db
[i] Checking integrity of /etc/pihole/pihole-FTL.db ... (this can take several minutes)

[✗] Integrity errors in /etc/pihole/pihole-FTL.db found.

To fix this you need to:

  • stop Pi-hole: sudo service pihole-FTL stop
  • rename the database: sudo mv /etc/pihole/pihole-FTL.db /etc/pihole/pihole-FTL-old.db
  • restart Pi-hole: sudo service pihole-FTL start
    A new database will be created.

Thanks! Problem solved!
