                        Hi! Does this also happen when you replace abort() with close()? Another thing: After calling abort(), is the finished() signal emitted?

                          And: On what platform do you observe this behaviour? Windows? Linux?

                            BTW: In your cancelDownload() function, it says:

                            reply->abort();
                            reply = 0;
                            

                            Looks like a memory leak to me.

                                      in

                                      Downloader::Downloader(QUrl Url, QObject *parent) :
                                          QObject(parent)
                                      {
                                          QNetworkRequest request(Url);
                                          DownloadManager.get(request);<<<<< THIS ?
                                      
                                          reply =  DownloadManager.get(request);
                                      

                                      you have extra DownloadManager.get(request);
                                      if I // it, it now drops to 0 when I abort.
                                      Before it did not.

                                        In my case, disconnecting all signals relating to QNetworkReply from all slots causes to abort() not works.

                                        disconnect(m_reply, nullptr, nullptr, nullptr);
                                        

                                        abort function works normal after commenting this line.
