Port 53 in use but shows nothing

Please follow the below template, it will help us to help you!

If you are Experiencing issues with a Pi-hole install that has non-standard elements (e.g you are using nginx instead of lighttpd, or there is some other aspect of your install that is customised) - please use the Community Help category.

Expected Behaviour:

Should install as usual

Actual Behaviour:

Installs but cannot start FTL (port 53 in use, but nothing shows up)

Debug Token:

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

Normal install, maybe note im using WSL 2 (Ubuntu). I disabled DNSStubResolver and sudo lsof -i -P -n | grep LISTEN shows nothing for port 53

Try this command:

sudo ss -tulnp '( sport = 53 )'


Not sure what this is

I thought sudo would show the process name.

Actually there is some process using port 53, but the command wasn't able to reveal the process name/PID, just like the debug log:

*** [ DIAGNOSING ]: Ports in use
[✗] udp:10.255.255.254:53 is in use by  
(...)
[✗] tcp:10.255.255.254:53 is in use by 
[✓] tcp:[::]:80 is in use by lighttpd

I decided to switch to docker so this isn't a problem anymore
