Hi,

Are you doing any delete call in your code ?

By the way, which version of Qt are you using ?
On what platform ?

[Kien Bui]

Sure. I used delete

I code and run at Linux (ubuntu14.04)
Qt5.2.
Addition, Am I wrong?

QNetworkReply *reply;
...
if (reply != nullptr)
    {
        reply->disconnect();
        reply->abort();
        reply->deleteLater();
        reply = nullptr;
    }

From the snippet you posted, you don't use delete but deleteLater. Why are you calling disconnect ? It will kill all connections done to the object.

@SGaist but when I use deleteLater() download progress still is working, I need stop download file immedicately

[SGaist]

Because the event loop has not yet processed every event thus the download might go some bytes further defore everything is processed.
