QNetworkReply and "unknown error" problem

[hybrid_snyper]

Hi,

I have seen this question raised on these forums and I feel I have done everything correctly so I was wondering if someone could help point out my fault.

So I have the following code that behaves as expected when there is a connection to the outside world, however when an error occurs errorString tells me there was an "unknown error". Why?

void myClass::checkInternetConnection()
{
    qDebug() << "checking internet connection";
    QNetworkAccessManager* am = new QNetworkAccessManager;
    connect(am, SIGNAL(finished(QNetworkReply*)), this, SLOT(onFinished(QNetworkReply*)));
 
    am->get(QNetworkRequest(QUrl("http://google.com")));
}

void myClass::checkInternetConnection()
{
    qDebug() << "checking internet connection";
    QNetworkAccessManager* am = new QNetworkAccessManager;
    connect(am, SIGNAL(finished(QNetworkReply*)), this, SLOT(onFinished(QNetworkReply*)));

    am->get(QNetworkRequest(QUrl("http://google.com")));
}

the slot, I would expect this to always be a QNetwokReply::NoError condition.

void onFinished(QNetworkReply* r)
{
    qDebug() << "Finished checking internet connection" << r->errorString();
    emit connectionVaild();
}

void onFinished(QNetworkReply* r)
{
    qDebug() << "Finished checking internet connection" << r->errorString();
    emit connectionVaild();
}

All the best
