MCC Multiplayer Canceling Immediately

So I just booted up MCC after a month or so on my PC and wanted to play a few matches before heading to work. When I tried to search for a session, the matchmaking search immediately cancelled and would continue to do so anytime I tried to rejoin matchmaking. I thought I may have been banned for some reason (if it matters, the last game I played I quit because Forge maps cause my PC to freak out with severe audio crackling and video lag, i was basically unplayable. This was, again, about a month ago) but there are no messages saying I’ve been banned from MP. Any advice would be very helpful and greatly appreciated.

If it matters, my PC is on the higher end. 8 Core, AMD FX-8300 3.3GHz, 8GB GeForce GTX 1070, 16GB RAM. I can run nearly every other game I own on the highest settings with no issues so I’m fairly certain something about Forge Maps is wrong (along with the audio crackling problem that I’ve seen other people on forums complain about).
