Hello, this error is triggered when the ROS master and node are on two different subnets, and the library cannot find an IP address suitable for communicating with the master. You need to set this IP manually through the Host parameter:

n, err := goroslib.NewNode(goroslib.NodeConf{
	Name:          "goroslib_pub",
	MasterAddress: "127.0.0.1:11311",
	Host: "my-ip-address",
})
if err != nil {
	panic(err)
}
