  Solutions
  
  
  Check Network Connectivity:
  
  Use tools like ping or traceroute to verify that the source system can reach the target system over the network.
  Ensure that any firewalls or network security settings allow traffic on the required ports.
  
  
  
  Verify RFC Destination Configuration:
  
  Go to transaction SM59 in the source system.
  Locate the RFC destination that is failing and check its configuration.
  Ensure that the hostname, system number, and other parameters are correct.
  Test the connection using the "Connection Test" button in SM59.
  
  
  
  Check User Authorizations:
