TLS initialization failed on GET Request

I'm starting with qt/c++ and on my project I need to make a json post/get/put but I'm trying to do a simple get request but I have an error: qt.network.ssl: QSslSocket::connectToHostEncrypted: TLS initialization failed

I don't know why, I tried some methods but all put the same message. I attach the code that I use.

mainwindow.cpp:

void MainWindow::replyFini(QNetworkReply* reply)
{
    QString answer = QString::fromUtf8(reply->readAll());
    qDebug() << "answer------------>"<<answer;
}

void MainWindow::on_btn_login_clicked()
{
    QNetworkRequest request(QUrl("https://httpbin.org/get"));
    QNetworkAccessManager *manager = new QNetworkAccessManager(this);
    connect(manager, SIGNAL(finished(QNetworkReply*)), this, SLOT(replyFini(QNetworkReply*)));
    manager->get(request);
}

mainwindow.h:

#include <QtCore>
#include <QNetworkAccessManager>
#include <QNetworkReply>

Solution

The SSL libraries are not found. The error can be read out in the Qt Src. Either deploy them with your application or install OpenSSL on your machine.

Also, just a small hint:

void MainWindow::replyFini(QNetworkReply* reply)
{
    QString answer = QString::fromUtf8(reply->readAll());
    qDebug() << "answer------------>"<<answer;
}

You should call reply->deleteLater();

void MainWindow::on_btn_login_clicked()
{
    QNetworkRequest request(QUrl("https://httpbin.org/get"));
    QNetworkAccessManager *manager = new QNetworkAccessManager(this);
    connect(manager, SIGNAL(finished(QNetworkReply*)), this, SLOT(replyFini(QNetworkReply*)));
    manager->get(request);
}

Add connect(manager, &QNetworkAccessManager::finished, manager, &QNetworkAccessManager::deleteLater);to avoid a memory leak on each click.
