Microsoft SQL Server 2017 - Developer Edition

I am facing a problem when trying to connect to MS SQL Server 2017

Database type = Microsoft SQL Server 2012+
jdbc:sqlserver = ‘sql server instance name’ / ‘database name’
— after testing connection I receive the following error
The TCP/IP connection to the host WIN-JUT92L32O69, port 1433 has failed.
Error: “Connection refused: no further information. Verify the connection properties.
Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port.
Make sure that TCP connections to the port are not blocked by a firewall.”.
— please note that I have added necessary rules at the firewall

Is there something wrong in the database definition or something else that I can test or check?

Thank you


Try the following:

  • Open the Microsoft SQL Server Configuration Manager (Start > All Programs > Microsoft SQL Server 2017 > Configuration Tool > SQL Server Configuration Manager)
  • Expand SQL Server Network Configuration > Protocols
  • Enable TCP/IP
  • Double Click on TCP/IP
    • Go to IP Adresses Tap
    • Set TCP port to 1433.


Thank you very much.
Issue is resolved.
I appreciate it.
