• What is the cause and solution for SAP error message 14450 - Web socket connection no longer exists ?

  The SAP error message "14450: Web socket connection no longer exists" typically indicates that there is an issue with the WebSocket connection between the client and the SAP system. This can occur in various scenarios, such as when using SAP Fiori applications, SAP Cloud Platform, or other web-based interfaces that rely on WebSocket communication.
  Causes:
  
  Network Issues: Intermittent network connectivity problems can lead to the WebSocket connection being dropped.
  Timeouts: If the WebSocket connection remains idle for too long, it may time out and be closed by either the client or server.
  Server Configuration: Misconfigurations on the server side, such as firewall settings or WebSocket settings, can prevent a stable connection.
  Browser Issues: Certain browser settings or extensions may interfere with WebSocket connections.
  Application Errors: Bugs or issues in the application code that manages WebSocket connections can lead to unexpected disconnections.
  
  Solutions:
  
  Check Network Connectivity: Ensure that there are no network issues affecting the connection. This includes checking for firewalls, proxies, or VPNs that might be interfering.
  Increase Timeout Settings: If applicable, adjust the timeout settings for WebSocket connections on both the client and server sides to allow for longer idle periods.
  Review Server Configuration: Ensure that the server is properly configured to handle WebSocket connections. This includes checking firewall rules and server settings.
  Browser Compatibility: Test the application in different browsers to see if the issue persists. Clear the browser cache and disable any extensions that might interfere with WebSocket connections.
  Application Logs: Check the application logs for any errors or warnings that might provide more context about the disconnection.
  Reconnect Logic: Implement logic in the application to handle reconnections gracefully when a WebSocket connection is lost.
  
  Related Information:
  
  WebSocket Protocol: Understanding how WebSockets work can help in diagnosing issues. WebSockets provide a full-duplex communication channel over a single TCP connection, which is essential for real-time applications.
  SAP Notes: Check SAP's support portal for any relevant notes or updates regarding WebSocket issues. SAP frequently releases patches and updates that may address known issues.
  Documentation: Review the official SAP documentation for the specific application or service you are using to ensure that you are following best practices for WebSocket connections.
