SSL Problem with private key

Question

public FTPSSession(FTPSConfigClass config)
{

SSLFTPClient client = new SSLFTPClient();
client.RemoteHost = config.Server;
client.ControlPort = config.Port;
client.ClientCertificate = SSLFTPCertificate.CreateFromPEM(config.CertificateFilePath);
client.ClientCertificate.AssociatePrivateKey(config.PrivateKeyFilePath, config.PrivateKeyPassword );

this.Config = config;
this.Client = client;

}

Is producing the following error in production, but not in test.

Consistency error: Private key was not successfully associated with certificate
at d1.b(String A_0, String A_1, Boolean A_2)
at EnterpriseDT.Net.Ftp.Ssl.SSLFTPCertificate.AssociatePrivateKey(String pvkFileName, String password)

Answer 1

This error generally means the certificate does not have a private key.
