Hi, you can refer to the thread below for the configuration part(the response to your other question).
[Unable to create the connection between MS SQL Server 2019 To Denodo 8.0](https://community.denodo.com/answers/question/details?questionId=9064u000000L8XkAAK&title=Unable+to+create+the+connection+between+MS+SQL+Server+2019+To+Denodo+8.0)
In addition to the thread above, I would also check if the TCP/IP connection to Port 1433 is allowed on MS SQL Server. Also, in general, I would check the firewall setting of the MSSQL server side if there is any setting blocking access from your denodo server or not.
Hope this helps!
