Loading Screen Crash

I started up league just like normal and I trying to play a game, it was going good I played maybe one or two games just fine but when I was trying to play a normal game with my friends at the begging of the match I disconnected so I restarted the client and logged back in as usual when I couldn't enter the game... every time I tried it kept saying I couldn't connect to the servers and to try again later. I have tried many different methods to work on this but none of them are working. Any help would be greatly appreciated.
