  Solutions:
  
  
  Check Network Connectivity:
  
  Use tools like ping or telnet to verify that the target system is reachable from the SAP system.
  
  
  
  Verify RFC Destination:
  
  Go to transaction SM59 and check the configuration of the RFC destination. Ensure that the connection type, target host, and system number are correct.
