I'm having the same issues. Been playing the game since launch with 0 connection issues. Today I played all morning fine, then this afternoon I try to go back in and getting constant disconnects. I'm not a computer person but I followed directions online to flush my dns. I reset my modem and router. I updated and restarted my computer. I'm not sure what else I should do. But as I said, I've been playing with no issues before today so I really doubt the problem is on my end.
