downloading the file problems

I am getting 403 error even I can download through the web.

Am I doing this wrong ?

the reply from finished()

Code:

---

if (_reply->error() || replyCode != 200) {
        qDebug() << _reply->errorString()  << " code: " << replyCode;
        return;
    }

---

Code:

---

void DownloadFromServer::GetTheFile() {
 
    qDebug() << "DownloadFromServer::GetTheFile()";
 
    QUrl url(_url);
    QNetworkAccessManager *http = new QNetworkAccessManager(this);
    QNetworkRequest request(url);
    _reply = http->get(request);
 
    connect(_reply, SIGNAL(finished()), SLOT(finished()));
    connect(_reply, SIGNAL(downloadProgress(qint64,qint64)), SLOT(downloadProgress(qint64,qint64)));
 
    qDebug() << "DownloadFromServer::GetTheFile() " << url.toString();
 
    _loop.exec();
}
