Что делать с ошибкой “Error creating SSL context ()”?

Делаю обычный Get-запрос. Вот код :

    QNetworkRequest request(URL);
    QNetworkReply *reply = manager.get(request);
    QEventLoop loop;
    connect(reply, SIGNAL(finished()), &loop, SLOT(quit()));
    loop.exec();
    qDebug() << reply->errorString();

Когда-то пользовался этим кодом, все работало. Сейчас почему-то получаю пустой ответ(без данных). Запросил errorString(), получил "Error creating SSL context ()". Подскажите, что с этим делать? Работаю в Ubuntu. Url рабочий, проверял.

UPD: При использование QSslSocket::supportsSsl(); получаем:
