QWebkit does not load from Url due to SslHandshakeFailedError

anshah

I'm seeing SslHandshakeFailedErrors in my Qt application when I try to load from a Microsoft Azure SAML url in QWebView on Ubuntu 22.04.
The result is just a blank QWebView window.

This same Azure SAML url was loading in Ubuntu 20.04.
Okta SAML url works in 22.04.

Here's a brief snippet of my setup:

// Setup
QWebView   *m_pView = new QWebView();
MyNetworkAccessManager* m_pNetworkAccessManager = new MyNetworkAccessManager();
m_pView->page()->setNetworkAccessManager(m_pNetworkAccessManager);

// QWebView: Connect signals/slots
connect(m_pView, SIGNAL(urlChanged(const QUrl&)),
        this,    SLOT(onUrlChanged(const QUrl&)));
connect(m_pView, SIGNAL(loadFinished(bool)),
        this,    SLOT(onLoadFinished(bool)));

// MyNetworkAccessManager: Connect signals/slots
connect(m_pNetworkAccessManager, SIGNAL(finished(QNetworkReply*)),
        this,                     SLOT(onFinished(QNetworkReply*)));
connect(m_pNetworkAccessManager, SIGNAL(sslErrors(QNetworkReply*, const QList<QSslError>&)),
        this,                     SLOT(onSslErrors(QNetworkReply*, const QList<QSslError>&)));

// Load
m_pView->page()->mainFrame()->load(m_url);

As one of the forums mentioned I should modify the SSL configuration so I reimplemented QNetworkAccessManager:

// Network Access Manager
class MyNetworkAccessManager : public QNetworkAccessManager
{

public:
    MyNetworkAccessManager();

protected:
    QNetworkReply* createRequest(Operation              op,
                                 const QNetworkRequest &req,
                                 QIODevice*             outgoingData = 0 );
};

// Network Access Manager
MyNetworkAccessManager::MyNetworkAccessManager() {}

QNetworkReply * MyNetworkAccessManager::createRequest(Operation              op,
                                                      const QNetworkRequest& req,
                                                      QIODevice*             outgoingData ){
    QSslConfiguration config = req.sslConfiguration();
    config.setPeerVerifyMode(QSslSocket::VerifyNone);
    config.setProtocol(QSsl::AnyProtocol);
    QNetworkRequest request(req);
    request.setSslConfiguration(config);
    return QNetworkAccessManager::createRequest(op, request, outgoingData);
}

After making these changes I'm still seeing the handshake errors in the onSslErrors slot and the QWebView window is still blank. Any help would be appreciated.

@anshah it is simple, just ignore ssl errors and continue
