can you help me out on what can be improved or use to a better communication between two machines? my case is at startup I can see the topics and nodes perfectly on my remote machine, and after I relaunching nodes again I won't see them anymore in my remote machine is this related to DDS that galactic is using ?

the workaround I'm doing that worked is to kill the ros2 daemon or I can just reboot the system

ROS2 - Galactic on an rpi
