  Cause:
  The error can be caused by several factors, including:
  
  Network Issues: Problems with the network connectivity between the hub and the backend system can lead to RFC failures.
  Configuration Errors: Incorrect configuration of the RFC destination or the system settings in the SAP system can cause this error.
  Authorization Issues: The user credentials used for the RFC connection may not have the necessary authorizations.

  Firewall Restrictions: Firewalls or security settings may be blocking the RFC communication.
  
  Solution:
  To resolve the ESH_EX017 error, you can follow these steps:
  
  
  Check Network Connectivity:
  
  Ensure that the network connection between the hub and the backend system is stable and operational. You can use tools like ping or traceroute to test connectivity.
