          So what's the problem here. IIUC Master's TcpAgent listener port is just inacessible from the agent machine. Check your network settings as a first step

          Well I have similar problem. My slave sends has a SYN_SENT status and while my Master is listening on the correct port, I cant seem to connect(Master doesnt send ACK) . I am using EC2 for both master and slave and I have opened all ports on slave for master's subnet and yet the connection times out.

          Will there be a new release for this issue. I updated to 2.121.3 recently and started getting this issue. Reverting back to older version also didn't help. I tried changing the port and then connection timed out problem got resolved but java.io.IOException: Failed to connect to xxxxxxxxxxxx:port is coming now.
