    Hi @KKIRUI,

    Thanks for your information.

    The error means the client cannot connect to SQL Server over the network. Here is a known issue like yours, you can follow steps to troubleshoot your issue:

    1. Make sure your database engine is configured to accept remote connections.
    2. You may need to create an exception on the firewall for the SQL Server instance and port you are using.
    3. Check if your SQL server services is up and running properly.
    4. Enable TCP/IP in SQL Server Configuration.

    Best regards,

    Lucy Chen
