Strange Connection Issues

I’m on Focused, first time I’ve played 5 in a while to see Firefight. I play one match, and get disconnected at round 1. Same thing happens for 2 or 3 more matches. Then I go to play Social Snipers, excited to finally see a new game mode, and I get disconnected. So I basically got banhammered for both arena and warzone. What’s happening?

The game is unstable. The only thing I can recommend is to go wired with an open nat. This eliminated most disconnects for me.
