the challenge asks you to log into this site http://165.227.106.113/post.php
Which gives you a message that states "This site takes POST data that you have not submitted!" when browsed to.

<!-- username: admin | password: 71urlkufpsdnlkadsf -->
Using post man to make a post request to this site with the form data in the source of the error reveals the code.
