Trouble connecting to server

So I am trying to connect to the friend safari but when I enter it asks if I want to connect to the internet then says connecting to server then just goes black. It worked fine a few days ago but all of a sudden it no longer works. Anybody have any ideas what I can do to fix this or is it not me?

Never mind, somehow it fixed itself.

Similar thing I have been facing recently, At times the screen goes black and at times it works , dunno what exactly is the cause :confused:

Your PC Firewall might interfere, also Speed-up button might cause it.
You can either re-start the game to fix it or wait several seconds and try again.
Adding the game at the Firewall exceptions is a possibility too.
