Didn't recive any lp after winning a ranked game.

So, I just won a ranked game. I clicked "continue" when the victory screen showed up, then, I couldn't see any stats in the post-game screen. I relogged and it did show me that I left a game and to reconnect. I tried to "reconnect" but since the game was finished, there was no game that I could reconnect to. I logged out and after a few hours I logged back in. No lp gain and the match doesn't appear in my history.
