Microsoft.Data.SqlClient.SqlException: '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)'

I have tried all the following:

1. Sql Server Agent configuration (start, stop, restart)
2. Sql Server Network Manager configuration: TCP/IP, Named Pipes, (enable , disable)

You should also consider solutions for other database providers (this did not work with Postgres).
