Thank you. Roscore This isn’t a bug or problem with ROS, however, since ROS topics use a publish/subscribe communication pattern8, and such patterns aren’t meant to be used for synchronous communcation.

If you tried running these two programs in reverse (first rostopic echo and then hello_world_node), there’s a chance that the “Hello, world!” message gets sent before rostopic echo has enough time

One of these things is on which machine and which port the ROS Master is running. If for some reason you have different settings in different terminals this would cause communication issues as well. So i try Name Resolution as suggested and changed the Hostname and associated Master URI to the System name and the IP address. I really appreciate that.
