I'm writing an Qt application and try to use Alexa API. I received access token, but I can't use API because of "Host not found" and "Connection closed".

My QNetworkAccessManager defined as

amazonHelper.data()->setNetworkAccessManager(
        view.data()->engine()->networkAccessManager());

...

void AmazonHelper::setNetworkAccessManager(QNetworkAccessManager *qnam) {
    qDebug() << "setNetworkAccessManager()";
    _manager = qnam;
    connect(_manager, SIGNAL(finished(QNetworkReply*)),
            this, SLOT(requestFinished(QNetworkReply*)));
}

After executing

_manager->connectToHostEncrypted("https://avs-alexa-na.amazon.com");

I receive an error "Host not found".

After executing

QNetworkRequest request(QUrl("https://avs-alexa-na.amazon.com/v20160207/directives"));
request.setRawHeader("Authorization", "Bearer %1" + _accessToken.toUtf8());
_manager->get(request);

I receive an error "Connection closed".

What is a right way to use Amazon Alexa API?

Thanks in advance!

P.S. I didn't find any actual C++ libraries. I found node-http2 library fo JS, but I don't want to use full stack of node.js in the app.

UPD1: I found QNetworkRequest::SpdyAllowedAttribute in Qt documentation but when I tried to set this attribute I got the follow error: 'SpdyAllowedAttribute' is not a member of 'QNetworkRequest'

UPD2: I tried to use libcurlcpp but after setting CURLOPT_HTTP_VERSION to CURL_HTTP_VERSION_2_0got exception (https://github.com/JosephP91/curlcpp/issues/84)
