Hi Guys

So I am doing the web proxy challenge and when going to the IP of the target machine I get the ping your IP ok.

When I put in /lucky.php I get Cannot GET /luck.php

Also when I open burpsuite and open the browser within burp suit and go to the target machine I cannot get their it just circle and circle.

Any help would be appreciated.

Many Thanks
