SQL Server error while connecting

Hi Rohanbhowmick 

Unfortunately I don't have a direct solution for you, but this should help. It discusses the issue you're facing in detail and provides a possible kerberos fix towards the end.

Cannot generate SSPI context when connecting to SQL Server - SQL Server | Microsoft Learn

Hope this helps.

Are you using Service principal authentication? if yes then does that SPN has permissions to access the db that you are trying to connect? 

Have you tried connecting to that db from other client tools like SSMS, excel and data studio etc? if yes then were you able to connect?

Gateway instllation is not required in your case.
