Nanoscan3 stop publish scan occasionally

[Huyhust13]

I have a project that deployed many AMRs into customer site from last year. Recently some of them suddenly stop publish scan. The sick_safetyscanners2_node still alive without any error log. I can ping to LiDAR IP. Some of them can resolve after relauch but one of them can't.
Here is the config:

sick_safetyscanners2_node:
  ros__parameters:
    frame_id: "laser"
    sensor_ip: "10.10.0.10"
    host_ip: "10.10.0.100"
    interface_ip: "0.0.0.0"
    host_udp_port: 6060
    channel: 0
    channel_enabled: True
    skip: 0
    angle_start: -2.2
    angle_end: 2.2
    time_offset: 0.0
    general_system_state: True
    derived_settings: True
    measurement_data: True
    intrusion_data: True
    application_io_data: True
    use_persistent_config: False
    min_intensities: 0.0

Anyone can please help?
