Hi Harishga,

Thank you for your quick response.

Yes. SQL Authentication is supported in my database server.

I have already installed a self hosted IR in my Azure Data Factory.

Ok. I will try the 3rd step and let you know.

Thanks,

Hi

We are trying to connect an on-prem sql server from our Azure ADF. There are firewalls involved. What are we missing . Please see the error :

"

Cannot connect to SQL Database. Please contact SQL server team for further support. Server: 'servertest.test.loc', Database: 'test_sirius', User: 'test\testdevsvc'. Check the linked service configuration is correct, and make sure the SQL Database firewall allows the integration runtime to access. A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server), SqlErrorNumber=53,Class=20,State=0, The network path was not found

Hello @Sivakumar Rajabather .

Currently, you are experiencing a network issue. There are two primary aspects to verify:

Firstly, if your SQL instance is within a virtual network, ensure that the machine you are connecting from resides in the same CIDR address space (subnet), or establish a VNET peering that allows connectivity to your SQL instance.

Secondly, if your Azure SQL instance is still assigned a public IP address—which is not recommended due to security concerns—make certain that appropriate firewall policies are in place to permit connections from your machine.
