  Causes of SWF_HTTP003
  
  
  Network Issues: Problems with network connectivity can lead to failures in RFC calls. This could be due to firewalls, proxy settings, or network outages.
  
  
  Configuration Errors: Incorrect configuration of the RFC destination or the HTTP connection settings can cause this error. This includes incorrect URLs, authentication issues, or missing parameters.
  
  
  Service Unavailability: The external service that the RFC call is trying to reach may be down or not responding.
  
  
  Authorization Issues: The user or service account used for the RFC call may not have the necessary permissions to access the external service.
  
  
  Timeouts: If the external service takes too long to respond, it may lead to a timeout error.
