Are you able to ping it via ethernet? When running the sudo ./low_level enxf8e43b808e06, if the leg is not suspended you will not be able to see any result, instead you can hear the motor resistance. If you are able to see the ros2 topics correctly then its mean setup is correct and only issue is the interface!
I’m having the same issue. Yet I can ping 192.168.123.161.
When I try the robot_state_client example, it appears the client connection is up. But not the server one.
I have the Go2 Pro model.
