  Causes:
  
  Malformed Request: The HTTP request being sent to the server may have incorrect syntax, such as missing headers, incorrect URL formatting, or invalid parameters.
  Invalid URL: The URL being accessed may not be correct or may not exist on the server.
  Incorrect HTTP Method: The HTTP method (GET, POST, PUT, DELETE, etc.) used in the request may not be appropriate for the endpoint being accessed.

  Test with a Tool: Use tools like Postman or cURL to manually send the same request to the server. This can help identify if the issue is with the request itself or with the eCATT configuration.
  Check Authentication: If the request requires authentication, ensure that you are providing the correct credentials and that they are being sent in the correct format.
  Consult Documentation: Review the API documentation for the service you are trying to access to ensure that you are following the expected request format.
