[help me] Connection failure error

Hi,
yesterday, after i finished a game, my LoL Cleint got crashed. Until then I can't log in on any account.
I have tried turning off my firewall/antivirus, adding lol launcher to trusted programmes, reistalling the game, restarting my router.
The worst thing is that it doesn't work on any computer in my house, so it can't be problem with this pc.
I hope you guys can find a solution, since LoL Support can only send me to another article with useless "guides".

regards,

WHAT is the problem?
Maybe u first calm down and make a screenshot?
Pics say more then a textwall...

Here is a screenshot of the error It shows up whenever I try to log in.
I didn't found my problem in your link, also solutions posted here by riot don't work.
Sorry for that panic, but I have customers, and i can't even run the game.
