Пример за Qt_HTTP SSL грешка:140A90C4:SSL процедури:SSL_CTX_new:нулев ssl метод е преминал

компилирах курса на този Qt примерен проект Qt_HTTP

след добавяне

QScreen *screen = QGuiApplication::primaryScreen();
QRect  availableSize = screen->geometry();

за да коригира грешката, тя се компилира добре. но всеки път, когато се опитам да отворя уебсайт със SLL връзка. получавам тази грешка:

Download failed:
Error creating SSL context (error:140A90C4:SSL routines:func(169):reason(196)).

използвайки командата на терминала:

$ openssl errstr 0x140A90C4
    error:140A90C4:SSL routines:SSL_CTX_new:null ssl method passed

Имам най-новата версия на OPENSLL: 1.1.1G

$ openssl version -a
OpenSSL 1.1.1g  21 Apr 2020

редактиране: Qnetworkrequest и конфигурация на ssl по подразбиране

чрез добавяне на този код: QNetworkAccessManager qnam;

QNetworkRequest request;
QNetworkReply* reply = qnam.get(request);

qDebug() << "Default SSL configuration isNull: "
         << QSslConfiguration::defaultConfiguration().isNull();

qDebug() << "SSL configuration used by QNAM isNull: "
         << reply->sslConfiguration().isNull();

получавам този резултат:
