Hi ,
   We get this exception in java as public class ConnectException extends SocketException
This just signals that an error occurred while attempting to connect a socket to a remote address and port. The connection is refused remotely (e.g., no process is listening on the remote address/port). Or a firewall perhaps, blocking your request  ..
Maybe its a 504 Gateway Timeout  
Connection timeouts occur when following steps happen:
1. The IP address for the requested server is successfully found
2. Connection establishment packets are dispatched to the IP address
3. The destination address deliberately ignores or does not receive them
Similar to connection timeout is Connection Refused, but in this case the destination system is actually sending packets back saying "go away, there is no service running on the port you are trying to connect to" 
Your packets are just being lost.. either the system or some intermediate system is firewalled.. if you can't connect using telnet, a browser or some other app, its a network problem.
Secondly there is a limit to number of conncetions the server can accept, Say for example after 250 it would not accept further conncetions. In java we can normally set the conncetion timeout period while we create the socket as per code shhown below
Socket s = new Socket(); s.connect(new InetSocketAddress(my_hostName, my_port), 60000);
This code waits for 60 seconds to get connceted. A timeout of zero is interpreted as an infinite timeout. The connection will then block until established or an error occurs. But PI has a default timeout period set, so if your timeout value is more than the default period, this code won't have any effect. You can increase the default timeout period for PI and check if this is working. You can use the following link or take help of your BASIS team to alter the TIMEOUT period
