MAC osX SSL issue SSLRead failed: -9842

ieio

Hi all,
I am new to QT-SSL, I started the http example and I added the following member function:
bool HttpWindow::loadPfxCertifcate2( ) {

QFile certFile("/Users/ieio/Qt/Examples/Qt-5.7/network/build-http-Desktop_Qt_5_7_0_clang_64bit-Debug/clientcert.pem");
if(!certFile.open(QFile::ReadOnly))
{
    QMessageBox::warning(this, tr("Http"),
                                   tr("Unable to open Cert file"),
                                   QMessageBox::Cancel);
    return false;
}


QSslCertificate certificate(&certFile, QSsl::Pem);
certFile.close();

&importedCerts, QByteArray::fromStdString(passphrase.toStdString()))

certFile.setFileName("/Users/ieio/Qt/Examples/Qt-5.7/network/build-http-Desktop_Qt_5_7_0_clang_64bit-Debug/cacert.pem");
certFile.open(QFile::ReadOnly);
QSslCertificate caCert(&certFile);
certFile.close();



QFile keyFile("/Users/ieio/Qt/Examples/Qt-5.7/network/build-http-Desktop_Qt_5_7_0_clang_64bit-Debug/privkey.key");
keyFile.open(QFile::ReadOnly);
QSslKey key(&keyFile, QSsl::Rsa, QSsl::Pem, QSsl::PrivateKey, "changeit");
qWarning() << key.isNull();

keyFile.close();

QSslConfiguration sslConfig = QSslConfiguration::defaultConfiguration();
QList<QSslCertificate> certs = sslConfig.caCertificates();
QList<QSslCertificate> localCerts = sslConfig.localCertificateChain();

localCerts.append(certificate);
certs.append(caCert);

sslConfig.setLocalCertificateChain(localCerts);
sslConfig.setCaCertificates(certs);
sslConfig.setPrivateKey(key);

 QSslConfiguration::setDefaultConfiguration(sslConfig);

return 1;

}

I call this function in the http constructor, just before the connect.
But when I try to download a page from my server I got the following error:
SSLRead failed: -9842

The same code works fine on Windows10 without any error.
Any idea?

Many thanks in advance,
i.
