L4D2 Connection Issues

Suddenly my Left 4 Dead 2 doesn't connect anymore to other games. I have been playing for some time and since the last week and a half, when I go for the on-line Campaign no rooms are displayed. I also noticed that the message with he number of players on-line is missing too.

Even when I try to open an on-line game I receive a message telling me that I should check my connection, but my connection is OK, I double checked.

I'm running a Linux Mint 64bit, 8GB RAM, 1TB HD and GeForce GTX 550 Ti Video board.

As I mentioned before, I always plays this game, and for the last month almost daily, and now suddenly I can't connect anymore to nothing else.

Hope you can help me, Steam Rocks!

Thank you in advance
