  Solutions:
  
  Check Network Connectivity: Ensure that there is proper network connectivity between the SAP system and the R/2 system. You can use tools like ping or traceroute to diagnose network issues.
  Review Configuration Settings: Verify the configuration settings for CPI-C in both the SAP and R/2 systems. Ensure that the connection parameters (like host, port, etc.) are correctly set.
