Connecting to game issue

This is an issue thats happened to me several times and its really starting to piss me off. Basically right after champ select is finished, an error notification pops up saying i cant connect to the game. It 100% is not an issue with my internet because i can do everything perfectly fine whenever this nonsense happens. Im tired of losing games and LP because im being kicked from the game with literally no way to get back in...not to mention you guys keep punishing me for this shit when its entirely out of my control.
