Please Help - I can not find any servers after the most recent update

Ever since the last update I have only been able to join the Germany 1 server for some reason. Whenever I try and net connect to a server it says connecting failed. I try and join my friends game through steam but it just takes me to the menu. Recently the Refresh Servers button has also stopped working and when it does it takes about 5 minutes to find the one German server. I have not found anyone else with a problem like this please help.
