When tracing a remote Gen application using the Dirgaram Trace Utility (DTU) the initial connection to the DTU listening port 4567 is successful but the subsequent Control Connection back to the server fails. The DTU console log shows:
Listening started, port: 4567
Detected V3 Session
Initiating session with "/server_ip:36610"
Failed to establish Control Connection with "server_ip:36611"
*** Not all debugging features will be available.
*** Often caused by a firewall preventing connections back to the client.
*** Reason: "java.net.ConnectException: Connection timed out: connect"
