Hi all. i have a function that uses qnetworkaccessmanager to send and receive files.

File sending.

....
QNetworkRequest req;
    req.setUrl(QUrl("https://192.168.2.1/input.php"));
    req.setRawHeader("Content-Type", "multipart/form-data; boundary=" + boundary);
    QNetworkAccessManager *manager = new QNetworkAccessManager;
 
    incoming= new QFile("file.xml");
    incoming->open(QIODevice::WriteOnly);
 
    connect(manager,SIGNAL(finished(QNetworkReply*)),this,SLOT(filesenderror(QNetworkReply*)));
    reply2 =manager->post(req,datas);
    connect(reply2,SIGNAL(readyRead()),this,SLOT(readfile()));
    connect(reply2,SIGNAL(finished()),this,SLOT(writefile()));
    connect(reply2,SIGNAL(finished()),incoming,SLOT(deleteLater()));
    connect(reply2,SIGNAL(finished()),manager,SLOT(deleteLater()));
    reply2->ignoreSslErrors();
    reply2->request();

    if (reple->error() !=0)
        {            
            if (reple->error() == 1 )

I'm developing on windows vista. Everything is running clearly on vista machines. But on windows 7, its returning ssl error that "Error Creating SSL Context".

I added Microsoft VC++ Redist packages to my inno setup file.

vcredist_x86.21022
vcredist_x86.30729.1
vcredist_x86.30729.17

Any ideas ? Am i missing something for windows 7 machines...

Regards.

--------------------------------

i copied openssl files, libeay32.dll and ssleay32.dll to application directory and problem solved.

Oh man, thank you very much. This was sooo annoying to debug. When making a QNetworkReply against an HTTPS address, it will silently fail with QNetworkReply::UnknownNetworkError and won't tell what's wrong.

I just can't thank you enough for sharing this solution!!!
