Running Pi-hole Docker Container with different docker port 80 mapping

gistfile1.txt

Issue: Changing the docker port 80 to hosted port not 80 causes the following message:
[ERROR]: Unable to parse results from queryads.php: Unhandled error message (Invalid domain!)

## Solution courtesy of unitpas, modified by kmagdziak

docker exec -it pihole apt-get update
docker exec -it pihole apt-get install nano
docker exec -it pihole bash

nano /var/www/html/pihole/index.php

change
$serverName = htmlspecialchars($_SERVER["HTTP_HOST"]);
with
$serverName = htmlspecialchars($_SERVER["SERVER_ADDR"]);

Ctrl+O to save
Ctrl+X to exit

reload web page

This also worked for me, looks like it needs to make it into the master branch.
