protocol "" is unknown QNetworkReply

Hi,

I have the following piece of code.

Code:

---

QNetworkAccessManager *man = new QNetworkAccessManager(this);
 
    QNetworkRequest getRequest;
    getRequest.setUrl((QUrl)requestUrl);
 
    m_svcReply = man->get(getRequest);
    connect(m_svcReply, SIGNAL(finished()),this, SLOT(getWebRequestFinished()));
    connect(m_svcReply, SIGNAL(error(QNetworkReply::NetworkError)),this, SLOT(webrequestFailed(QNetworkReply::NetworkError)));

---

If I'm executing this request over WIFI, I get a proper response from the server.
However if I'm executing this request over 3G, I get a protocol "" is unknown error.

Any ideas why this might be happening?

Thanks

What is the content of requestUrl?
