This looks very similar to this issue. Maybe you have a similar configuration error?

It is not clear from your problem description whether this is a network issue or an configuration issue.

So the first thing i would suggest is to check for full connectivity using pin/netcat. Keep in mind that ROS requires full bi-directional connectivity between all pairs of machines, on all ports.

Moreover make sure your ROS_MASTER_URI, ROS_HOSTNAME / ROS_IP is set correctly on all machines.

• In general ROS_MASTER_URI has to be set on each remote machine toROS_MASTER_URI=http://<hostname>:<used port> or http://<master ip>:<used port>
• On the machine running the master you do not necessarily have to set ROS_MASTER_URI explicitly as it defaults to http://localhost:11311, however, if using a custom port (as in your case) set it to http://localhost:<used port>
• ROS_HOSTNAMEonly has to be set manually on a machine if your systems default host names is not resolvable.
• Alternatively to avoid taking care of the name resolution you can set ROS_IP to your external IP Address on each machine without a resolvable host name.

A basic tutorial on how to test and setup your network for ROS can be found here.

For a more specific answer please provide more details about your network configuration and your ROS environment.
