Can't join any game

It's been days since I could play one game of league ! Every time everything s fine, I can lock my champ and all until it comes to actually loading the game. It's just stays as a black screen and the message "Failed to connect: Unable to connect to the server. Please check your networrk connection and attempt to reconnect to your game" comes up After that it's litteraly unpossible to join that damned game.

to reproduce the bug I need to: 1 - try and launch any league of legends game (I've tried custom and normal draft) My connection's looks fine you're the only game not working I've even tried uninstalling relaunching disabling my firewall my antivirus launching lol alone restarting my pc it seams that I've tried everything

It happened every single game I tried to launch except once when I managed to launch a custom alone! after that custom I tought you had fixed the issue but I was put back into the black screen of death just after trying to launch another one.

It looks like a bug that you could encounter like last year but this time I haven't seen many people complaining...

I'm getting sick of it and I was put into the low priority queue because of that! Could you please fix this ?!
