Well yesterday the server list is working and i can join any server but today i cant .i tried to turn off my firewalls but it didnt work. can someone help me?

I assume you were logged in and hit the refresh button? :?

i did but still nothing

Are you sure that you're on "internet" tab?

It's really weird that it suddendly just stopped working for you...

When you hit refresh does your internet automatically disconnect?
