  Configuration Issues: There may be misconfigurations in the monitoring setup or in the monitored service.
  Timeouts: The request to the monitored service may be timing out, leading to a lack of response headers.
  Firewall or Security Settings: Firewalls or security settings may be blocking the communication between the monitoring system and the monitored service.
