Don't change the port during an update


every time after an update of pihole i have to change to port of pihole back to my port.
Is there any need to change it every time back to 80?


HTTP requests go to port 80, so to return an empty page for ads, we need to listen on port 80.

As @Mcat12 said, pi-hole has to have port 80 to serve a transparent pixel in place of http ads.
You could run either of the two on another network interface/IP?
