File upload error with Qtnetworkaccessmanger 5.12

Question

I am trying to upload a json file to my server using QtNetworkAccessManager. But on the execution time of program gets error like connection closed or unknown error. Any one can help me to correct those error

upload = new QNetworkAccessManager(this);
connect(upload, &QNetworkAccessManager::finished, this, &Cricbang::uploadFinished);
match_file=new QFile("saved/upcoming_match_list.json");
QFileInfo fileinfo(*match_file);
url.setUrl("http://serverIPadress/cricket/" +fileinfo.fileName() );
url.setUserName("userName");
url.setPassword("password");
url.setPort(22);
if (match_file->open(QIODevice::ReadOnly)){
    QNetworkRequest request(url);
    rsult=upload->put(request, match_file);
}

upload function

 void Cricbang::uploadFinished(QNetworkReply* reply) {

   if (!reply->error()) {
       match_file->close();
       match_file->deleteLater();
       reply->deleteLater();
       QMessageBox::information(this, "upload", "finished");
   }
   else
   {
       QMessageBox::information(this, "error", reply->errorString());
   }
}
