When i try to login to any premium server, I get Java has stopped working for 30 seconds aproximately. After The client is returning me : "failed to login: java.net.ConnectException: connection timed out: connect" !

In plus I have noticed that when I try to access https://session.minecraft.net, i get same from Google Chrome. However mojang.com, minecraft.net are still working perfectly.
Your skining & download server is ok.

When i try to log into offline mode servers (like cracked ones), I get no problems...

Please help me.
Hope you can help me...
