Problem

Hey. I am trying to use socket.io with Chrome 17 but it cant connect in 40% of the cases and says "WebSocket is closed before the connection is established.". At times it works perfectly. I am using the latest socket.io version with the latest nodejs, on Windows both, cross domain. Any ideas? Cheers
