The challenge gives a url named /header.php, we got blocked whiling access the page

Sorry, it seems as if your user agent is not correct, in order to access this website. The one you supplied is: chrome 
<!-- Sup3rS3cr3tAg3nt  -->

Changed the user agent to Sup3rS3cr3tAg3nt and visit again, we got a new hint

Sorry, it seems as if you did not just come from the site, "awesomesauce.com".                  
<!-- Sup3rS3cr3tAg3nt  -->

Now we change the referrer to awesomesauce.com and try again

curl -v -H 'User-Agent: Sup3rS3cr3tAg3nt' --referrer awesomesauce.com http://165.227.106.113/header.php
