Dataflow not able to access PBI Warehouse

So far tried to access Warehouse through Fabric.Warehouse, SQL Server database connectors. In dataflow v1 I have not been able to access the data in the warehouse.

When tried SQL Server database in Power BI desktop I can see the data. In gen2 Dataflow Im able to access the Warehouse via Fabric.Warehouse connector.

So far getting this errror:
Fabric.Warehouse:

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)
