CSC is right…It could also be that the server is down, the 3030 service is down or the server is unreachable. Can you still connect to that VM server using other means (remote desktop,FTP, anything)? Can you telnet to the 198.164.157.214:3030 and get any “response”?
IP address: 198.164.157.214
ISP: University of New Brunswick
Organization: New Brunswick Community Colleges - Committee
City: Fredericton
Region: New Brunswick
Country: Canada (CA)
So being a University network, this machine most likely sits behind a firewall and port 3030 is not open for incoming connections.
