Debug Token:


I am running on a debain stretch and have been for months. Last night it stopped working. I shutdown that instance and brought up a second. I did all updates to OS and PIHOLE. only status I can find is DNS service is not running. Any help would be great.


Your debug log shows that piHole-FTL is not running:

*** [ DIAGNOSING ]: Ports in use
*:80 lighttpd (IPv4)
*:80 lighttpd (IPv6)

*** [ DIAGNOSING ]: Name resolution (IPv4) using a random blocked domain and a known ad-serving domain
[✗] Failed to resolve fili.tv via localhost (
[✗] Failed to resolve fili.tv via Pi-hole (
[✓] doubleclick.com is via a remote, public DNS server (

Try running this command to restart FTL.

sudo service pihole-FTL restart

If that does not resolve it, reset your namserver to a public DNS and then repair

sudo nano /etc/resolv.conf

Change to, save and exit

pihole -r and select “repair”


The FTL restart did not work.
Repair did not work.

[✓] Enabling pihole-FTL service to start on reboot
[✓] Deleting existing list cache
[✗] DNS service is not running
[✓] Starting DNS service
[✗] DNS resolution is not available

So I did a reboot and did not work either. I had already done the repair several times.



Please upload another debug log and post the token.




I have not seen a reply to the last diagnostics. Let me know if I need to provide another.


Run this command and post the output:

pihole checkout master
