It’s working for me as well now, before I was getting the following error:
This site can’t be reached
http://www.mightyape.com.au’s server IP address could not be found.
Checking the connection
Checking the proxy, firewall, and DNS configuration
So I changed my desktop to Googles DNS and it could resolve so assumed it was blocked when using the family filter. I’ve re-tested and can confirm it’s working when using 22.214.171.124.
