Madden Connected Career Problem

I'm in a connected career with a bunch of friends and had this problem for the second time tonight. Anytime we try to get in to the lobby to begin the game, we constantly get a "session no longer available message". It does the same thing regardless if we try to accept game invites or just go meet in the lobby. We tried restarting, signing out/in, etc.

I tried searching online and it seemed as if other people had the same problem before, but didn't find anything saying how to fix it. Anyone?
