Connect AWS PostgreSQL to Power BI Desktop:The specified hostname was not present in the certificate

Question

I am trying to connect my PostgreSQL database to my Power BI desktop.

I downloaded the certificate from https://s3.amazonaws.com/rds-downloads/rds-combined-ca-bundle.pem and installed in my machine. I am getting the same error as follows

Details: "An error happened while reading data from the provider: 'Npgsql.Tls.ClientAlertException: CertificateUnknown: Server certificate was not accepted. 
 Chain status: A certificate chain processed,
 but terminated in a root certificate which is not trusted by the trust provider.
. The specified hostname was not present in the certificate.
   at Npgsql.Tls.TlsClientStream.SendAlertFatal(AlertDescription description, String message)
   at Npgsql.Tls.TlsClientStream.ParseCertificateMessage(Byte[] buf, Int32& pos)
   at Npgsql.Tls.TlsClientStream.TraverseHandshakeMessages()
   at Npgsql.Tls.TlsClientStream.<GetInitialHandshakeMessages>d__43.MoveNext()
--- End of stack trace from previous location where exception was thrown ---
   at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)
   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)
   at Npgsql.Tls.TlsClientStream.<PerformInitialHandshake>d__72.MoveNext()'"

My Npgsql version is 3.2.2.

Certificates are successfully imported like this.

I really do not know why is it still showing the error. Can somebody help me with this?

Answer 1

I could finally access the database with an ODBC driver.

Select Others from Get Data list and select ODBC. Add the driver(if required) and set up the data source. Input your credentials and connect.

Good to go!
