Continuus Connection Error

Hey so i got on my computer today and i went to play some league just like i would any other day and the darn league client wont let me log in it will literally just sit on "Logging in..." then after a few minutes it just tells me connection error. now ive tested this with a few accounts of mine because i have one that i just play with my new friends on and ive tried it with a different computer and have gotten the same resaults every time. is there anyway anyone can fix this for me.

P.S. Yes ive tried restarting my computer and league and restarting my internet and repairing the league client.
