The Pihole webserver isn't working properly

[Greg5678]

So, I'm running on a Pi 4 8 GB and I have a few different applications like the acupsd webserver as well as Netdata that may be causing issues. FYI the Pi acts as router. Netdata runs on port 19999 and the acupsd webserver runs on port on port 80 "192.168.220.1/cgi-bin/apcupsd/multimon.cgi".

Since you already have Apache running on port 80, lighttpd (the shipped web server) won't bind to that port.

You have a few options:

 Remove Apache (may not work in your use case), or

Move Apache to a different port, or

Move lighttpd to an alternate port:

A permanent method of changing the lighttpd port (for lighttpd version 1.4.46 or later):

Check your lighttpd version with this command.

lighttpd -v

If that returns 1.4.46 or above, you can overwrite the port from Pi-hole's lighttpd.conf in your external.conf like this:

server.port := 8888

Note that the := operator isn't supported in older versions of lighttpd .
