One of my messages in the thread you referenced should solve your problem. Your problem is related to running the web user interface on a non-standard port (i.e. not 80). We changed our security policy lately to also allow custom ports.

Note, that you can also whitelist domains using the command line interface (CLI):

```auto
sudo pihole -w abd.ce def.com ghr.co.uk

```
