Black Ops Cold War - Can't connect to server?

I recently purchased BOCW, and no matter what I do, I cannot connect to the server, and I’ve tried several troubleshooting methods, like running as admin and repairing the file. I know my connection is fine and my pc can handle it (GTX 1080, i7 7700k), I just can’t get it to connect to the server for some reason. I was able to play the game on an alt, but that’s because there is a free time-period for multiplayer and zombies (and have no access to the campaign), and it says as much when I play the game on that alt. I know for sure I purchased the game via my main email, I have the receipt in my inbox.
