This problem follows the same specifications as the previous Verticode problem, except that you have to solve many of them by developing a client to communicate with the server available at problems1.2016q1.sctf.io:50000. Good luck.

I tried to connect with nc and the server was printing an HTML page like this
And wait for our response (the solution for that Verticode).
So I edited the previous script with some Networking and Base64 Library. Done.
