@Ragunathan46 Thanks. Looks like your user cannot access SQL DB. Any chance to test the SQL DB User? Please try SSMS and login directly to SQL DB with given credentials. Then we can check oft this works. You can get it here: Download SQL Server Management Studio (SSMS) - SQL Server Management Studio (SSMS) | Microsoft Learn

I saw this and changed application pool identy then success.

But I don’t know why I can’t follow the official tutorial,need to do this.

Can someone explain?
