I got "kicked out of my ranked game"

Hello I just wanted to bring this up. I was playing ranked today and we were winning. Out of nowhere it said I dced so I waited about 2 minutes....nothing. So I left my game(so I could then reconnect manually). After I left, my game was updating for no reason. I thought it was a glitch, so I restarted my client. It still had to update. It finished then boom nothing. The game is still going on and I can't even reconnect. How am I supposed to play a new game knowing that my team might lose because of me. It lets me play a new game, but I can't reconnect to the one I was in. I restarted my laptop, I restarted my client nothing. If I get banned for this I'm gonna have problems.
