      delete connect(apiQuery, &QNetworkAccessManager::finished, this, &MainWindow::testSlotFromQDebug);

      then:

      void MainWindow::on_testButton_clicked()
      {
          QNetworkRequest request;
          request.setUrl(QUrl("https://www.alphavantage.co/query?function=TIME_SERIES_INTRADAY&symbol=MSFT&interval=5min&apikey=demo"));
      QNetworkReply* reply = apiQuery->get(request)
          connect(reply ,&QNetworkReply::finished,this,std::bind(&MainWindow::on_reply,this,reply ));
      }
      void MainWindow::on_reply(QNetworkReply* reply){
      QJsonDocument jdoc = QJsonDocument::fromJson(reply->readAll());
      // do something with the jdoc
      }

        Qt says: qt.network.ssl: QSslSocket::connectToHostEncrypted: TLS initialization failed
        I have api-key: 63YUZ8NP5SW1D302
        How can I use the key?

          Make sure you have OpenSSL installed

          I have api-key: 63YUZ8NP5SW1D302
          How can I use the key?

            This link is nothing about OpenSSL.
            OpenSSL need to connect to the project?

              Qt uses OpenSSL to implement TLS and SSL

                I installed everything in MaintenanceTool. Do I need to download additional OpenSSL?
                If you need to install OpenSSL, then how to connect it to Qt?

                  What OS are you on ? My guess would be Windows.

                        downloaded openssl-1.1.1b and put it in the folder with the executable file. Did not help.
                        In openssl-1.1.1b there is no libeay32.dll.

                                  Then try again with the latest version of the 1.0 series.

                                    I downloaded openssl-1.0.2r. There is no bin folder. No .exe files. No libeay32.dll. What to do with it?
