I cannot get my xbox 360 to connect to the Mezzmo server (Windows Server 2008r2)

I have opened up the ports on both the router and the computer.

Mezzmo works just fine on playstation 4 before I messed with any ports.

Checked the profile to make sure it was allowed and set to XBox 360

I can access the server from the browser on my internal network.

I can send music from the android app to xbox without any problems.

What I CAN'T do is connect to mezzmo using the music app on XBox 360, so I can play music in the background while I game.

I searched the forums and have not found an answer to my problem.

Please help!
