Maybe it is the daemon that stopped working? Can you try again after ros2 daemon start?

The daemon is not required for ros2 communication to work

Jetson's ros2 work well but I can't see its topics and nodes from another computer when it came back to network. I think the problem is in dds. How can I configure fast dds settings?

You might try 'ros2 multicast receive/send' at both endpoints to see if multicast is being passed through when this happens.
