[Client] Missing LP

I just played 2 games back to back and won both of them. The first game I gained 20 LP then went on to the next. the next game and my most recent one I won but at the end was disconnected after we had won so I couldn't see the post game lobby but after looking at my profile I noticed that I was back down to 0 Lp then immediately disconnected from the servers and I can't connect back.
