This error typically arises in scenarios where SAP CRM is trying to communicate with external systems or services, and the connection is interrupted or not established properly.
  Causes:
  
  Network Issues: There may be network connectivity problems between the SAP system and the external system or COM server.
  RFC Gateway Configuration: The RFC Gateway may not be configured correctly, or the gateway service may not be running.
  COM Server Issues: The COM server may be down, misconfigured, or not reachable.

  Authorization Issues: The user or service account may not have the necessary permissions to access the RFC or COM server.
  Resource Limitations: The server may be running out of resources (e.g., memory, CPU) which can lead to disconnections.
