@MrWick, this port: 33168 is the port on which your instance = a.k.a → the challenge your solving is running. All of the ports in section: Web Challenges that you will see after the IP of the instance are a web pages. That means you can go the web page of the challenge and from there you will be able to solve the challenge.
E.g. → host: (IP_of_Challenge) port:33168 → http://(IP_of_Challenge):33288
Hope I helped
Good luck
