  The SAP error message /IWXBE/CORE228 Connection test failed. Daemon is not running.

This error is often related to the SAP Process Integration (PI) or SAP Process Orchestration (PO) environment.
  Causes:
  
  Daemon Not Running: The most common cause is that the required daemon (background service) for the communication channel is not running. This could be due to a crash, improper configuration, or it was never started.
  Network Issues: There may be network connectivity issues preventing the SAP system from reaching the external service.
  Configuration Errors: Incorrect configuration settings in the communication channel can lead to connection failures.
  Resource Limitations: The server may be experiencing resource limitations (CPU, memory) that prevent the daemon from running properly.
  Firewall or Security Settings: Firewalls or security settings may be blocking the connection to the external service.
  
  Solutions:
  
  
  Check Daemon Status: Verify if the daemon is running. You can do this by checking the relevant logs or using transaction codes like SXMB_MONI or SXI_MONI in SAP PI/PO.
  
  If it is not running, try to start or reactivate the daemon.
  
  
  
  Reactivate the Channel: If the daemon is running but the error persists, try reactivating the communication channel. This can often resolve temporary issues.
  
  Go to the Integration Directory, find the relevant communication channel, and reactivate it.
  
  
  
  Review Configuration: Check the configuration of the communication channel for any errors or misconfigurations. Ensure that all parameters are set correctly.

  Review Logs: Check the logs for any additional error messages that might provide more context about the failure. Look in the SAP application logs or the logs of the external service.
  
  
  Resource Monitoring: Monitor the server resources to ensure that there are no limitations affecting the daemon's ability to run.
