Problem that i never had - Some help please

[LAB~MONSTER]

This is what I can do. I am able to connect to all the available servers.

When I quick match someone it doesn't work. also when someone quick match me it doesn't work.

I am able to host but no one is able to join.
I can't join anyone's game.

So basically i can't get any challenges or challenge anyone. is there something i have to disable or enable to make this work. Help me plz.
