As another student pointed out that if you try creating a session from either view port or by launching a seperate game and then try joining from the other way, it would fail to join a session due to different ports showing up. For me it was defaulting to port 0 no matter how I launched. The work around for me was to just launch two seperate game instances from the directory and not use the view port. So for now, I am just advising that you test by launching the game twice from your project directory and not your viewport. Or as the TA pointed out, you can also use command line. Which ever you prefer.
