QNetworkRequest https problem connect missing reply

[Linux5445]

I know, I just want to have the id like this in the web site:
<input type="hidden" name="lt" value="_cC02BDB12-D1D9-7155-261D-9D1174D68BD3_k4E4C0CC3-872E-EA91-456C-A29E1E0B4CF5" />

I was using this method for the sslError but i don't have any error:

void FenPrincipale::ErreurSsl(const QList<QSslError> & errors) 
{
	qDebug () << "errorSSl";
	for (int i=0; i < errors.length(); i++)
	{
		qDebug() << "errorSSl = " << errors[i].errorString();
	}
}

void FenPrincipale::ErreurSsl(const QList<QSslError> & errors) 
{
	qDebug () << "errorSSl";
	for (int i=0; i < errors.length(); i++)
	{
		qDebug() << "errorSSl = " << errors[i].errorString();
	}
}

Why i don't have any SSL error ? why the web site return nothing (no redirection) ?
