Velodyne poll() timeout

[hxj0316]

Hello, I compiled vlp_driver under ros2, and then I ran the "ros2 run velodyne_driver velodyne_driver_node" command, and the result was as shown in the figure below. I pinged the address of the lidar, and it was able to ping. , I don’t know why there is such a problem, please help me to take a look, thank you.
