Cant reach admin interface with port 8080

The issue I am facing:
I try to access to http://192.168.1.30:8080/admin and the request times out after 2minutes

Details about my system:
raspberry pi bullseye

What I have changed since installing Pi-hole:
I created the /etc/lighttpd/external.conf with the line server.port := 8080

Debug token vXv9B51H

My error and apologies. I was reading a different user's debug log (had two open in my browser).

Your active IP is: eth0 (192.168.1.30)

Your debug log does not show lighttpd running on any port.

Something is cycling lighttpd:

I thought that this line showed that lighttpd was running on port 8080, isn't it the case ?

Besides when I run wget localhost:8080/admin from the raspberry console I get an admin html file which let me think that lighttpd was running.

My error. It is running on port 8080.
