Below are the potential causes, solutions, and related information for this error:
  Causes:
  
  Network Issues: There may be network connectivity problems between the application server and the HANA database server.
  Configuration Errors: Incorrect configuration settings in the SAP system or HANA database can lead to connectivity issues.
  Database Availability: The HANA database might be down or not running, which would prevent any connections.

  Solutions:
  
  
  Check Network Connectivity:
  
  Use tools like ping or telnet to verify that the application server can reach the HANA database server on the required port (default is 30015 for HANA).
  
  
  
  Verify HANA Database Status:
  
  Ensure that the HANA database is up and running. You can check this using the HANA Studio or command line tools.
  
  
  
  Review Configuration Settings:
