For me, i have the same issue but after i complete a match. No matter if i win or lose, it will lag and the say "lost connection to server try again later" and it would appear again if i hit "okay" then all it would be is a loading screen that doesn't go away. after that i tried closing out and trying again, but its just a black screen. i redownloaded it and it worked! but for only one game, having the same issue.
