DNS server failure

Help

Hi all

All of a sudden I get a DNS server failure on my Pihole (Core v6.1.4 FTL v6.2.3 Web interface v6.2.1)

Here is my token: https://tricorder.pi-hole.net/qyDPMd6j/

Can anyone please let me know what could be the issue?

PS: I even reinstalled my pihole...still no go :frowning: DNS server failure

Thanks in advance

You have another DNS server (connmand) running on your OS and using port 53:

*** [ DIAGNOSING ]: Ports in use
(...)
[✗] udp:127.0.0.1:53 is in use by connmand 
(...)
[✗] tcp:127.0.0.1:53 is in use by connmand

Pi-hole needs this port to work. When this port is already in use, pihole-FTL fails to start:

2025-09-02 18:37:10.559 CEST [1447M] CRIT: Error in dnsmasq configuration: failed to create listening socket for port 53: Address in use

Many thanks. I was able to fix the issue following the guide here: Port 53 bound after installation of May update? - #5 by sam_nazarko - Raspberry Pi - OSMC Forums
