Can't connect to a game problem!

It was working fine earlier today but now I can’t get any matches at all. It keeps saying the connection was lost. Is anybody else having network issues like this? I live in central USA and shouldn’t have this problem popping up.

Anybody at all have this problem? Nobody?

I do too…It started over the weekend and i thought I was banned but I never received a message. I group up and when it is loading the game it says "Connection Lost you have been disconnected from the local network. returning to main menu
Help!!
