Currently, I have created a new database, taken the connection string, put it in the application asp.net core, and activated remote access, but when I update the database, this error appears: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. 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)
It also refuses to open the database on SQL Server
