QNetworkAccessManager send data incomplete on windows

[aidinMC]

I have a trouble with QNetworkAccessManager in windows. I wrote the following code to submit request ,it works on ubuntu perfectly but on windows send just 16384 bytes!! It seems request execute just once and freeze.

QString concatenated = username + ":" + pass;
QByteArray hash = concatenated.toLocal8Bit().toBase64();
QString headerData = "Basic " + hash;
QNetworkRequest request = QNetworkRequest(QUrl(baseURL));

request.setRawHeader("Authorization", headerData.toLocal8Bit());
request.setRawHeader("Content-Type", "application/json");

QNetworkReply * reply = nam->post(request,data);
connect(reply,&QNetworkReply::uploadProgress,this,&myClass::uploadProgress);

in uploadProgress method:

qDebug() << sent << " " << total;
if(total && sent){
    int result = (sent*100)/total;
    emit uploaded(result);
}

output:

16384 632054 // AND EVERY THINGS STOP UNTIL I GET QNetworkReply::RemoteHostClosedError ERROR CODE

Is your host really consuming the bytes sent under/from Windows? Looks like a buffer has been filled but not read out?

How can I check it?
May it Qt bug on windows 10?
Because this code works perfectly on Ubuntu and I sent over 500MB data to server!

I tested this code too, The result no change:

QString concatenated = username + ":" + pass;//username:password
QByteArray hash = concatenated.toLocal8Bit().toBase64();
QString headerData = "Basic " + hash;
QHttpMultiPart *httpMultiPart = new QHttpMultiPart(nam);
QHttpPart *httpPart = new QHttpPart();
httpPart->setRawHeader("Authorization", headerData.toLocal8Bit());
httpPart->setRawHeader("Content-Type", "application/json");
httpPart->setBody(data);

httpMultiPart->append(*httpPart);

QNetworkReply* reply = nam->post(QNetworkRequest(QUrl(baseurl)),httpMultiPart);

@aidinMC
I don't know what your issue is. But is this your only code? You don't want to put in any code for, say, errorOccurred or finished or anything else?

After two days finally, I found why it happened! It because I emit the signal in uploadProgress directly! I changed the uploadProgress code like below and it works perfectly now!

qDebug() << sent << " " << total;
if(total && sent){
    int result = (sent*100)/total;
    QTimer::singleShot(5,[this,result](){
       emit uploaded(result);   
    }
}
