          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 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.
