Hi @ivamsikrishna 
It looks like the error is due to a network issue between Microsoft Fabric and your on-prem SQL Server—most likely from the gateway (Self-hosted Integration Runtime). Make sure the gateway is running and can connect to your SQL Server (you can test it using SSMS on the same machine). You can also try using Dataflow Gen2 as a workaround, which sometimes avoids these connection issues.
