Launcher Error Bug

Almost every time recently, when I launch LoL, and log in, it will give me an error about no connection or something, I don't exactly remember what it says, as it only happens once a day as far as I know, so I'd have to wait till tomorrow for an exact wording, but what it does is after logging in the first time, it will say "Authentication Authorized" Or whatever it says when you log-in with the right info, and then an error pops up and closes the game and I have to re-launch the game and log-in again. It's not that big of a deal, but it's slightly annoying.
