Hi @Laxendra ,

I found the relevant link and I think you can look into it:

A network-related or instance-specific error occurred - SQL Server | Microsoft Learn

Once I've connected to SQL Server and configured the gateway, selecting a corresponding destination allows me to store it.

Yes i have on prem data gateway and i am able to see all tables on prem server, but when i configure my destination as onelake that time i get this error message

As this is an On Prem server, are you using On Prem data gateway? And can you plz confirm whether the server on which the gateway was set up is able to acess the On Prem SQL server?
