@ARASHz4
connect to QNetworkAccessManager's sslErrors() signal and check why it is called.

@ARASHz4, Hi, link your project with openssl libraries libssl and libcrypto and it will be ok.....

raven-worx

@stephane78
They are loaded when needed, so absolutely no need to link against them and introduce another dependency.

@raven-worx i connect sslErrors :

connect(reply, SIGNAL(sslErrors(QList<QSslError>)), this, SLOT (sslErrors(const QList<QSslError>&)));

but don't call sslErrors
when i start a download in my app, in application output return this :

qt.network.ssl: QSslSocket: cannot resolve TLSv1_1_client_method
qt.network.ssl: QSslSocket: cannot resolve TLSv1_2_client_method
qt.network.ssl: QSslSocket: cannot resolve TLSv1_1_server_method
qt.network.ssl: QSslSocket: cannot resolve TLSv1_2_server_method
qt.network.ssl: QSslSocket: cannot resolve SSL_select_next_proto
qt.network.ssl: QSslSocket: cannot resolve SSL_CTX_set_next_proto_select_cb
qt.network.ssl: QSslSocket: cannot resolve SSL_get0_next_proto_negotiated

@ARASHz4
Do you have the SSL libraries available (globally installed and available in %PATH% or copied into the folder that contains your exe)?

ARASHz4

@the_ No

in install OpenSSL in my system after i installed this in application output don't return this:

qt.network.ssl: QSslSocket: cannot resolve TLSv1_1_client_method
qt.network.ssl: QSslSocket: cannot resolve TLSv1_2_client_method
qt.network.ssl: QSslSocket: cannot resolve TLSv1_1_server_method
qt.network.ssl: QSslSocket: cannot resolve TLSv1_2_server_method
qt.network.ssl: QSslSocket: cannot resolve SSL_select_next_proto
qt.network.ssl: QSslSocket: cannot resolve SSL_CTX_set_next_proto_select_cb
qt.network.ssl: QSslSocket: cannot resolve SSL_get0_next_proto_negotiated

@ARASHz4

Do you get any errors when you try to download the file?

ARASHz4

@the_ yes, the error is:

Host https not found

the_

@ARASHz4

Maybe you can post some code how you try to download the file?
Our USB crytall ball is currently not working ;)

ARASHz4

@the_ this is my project :
https://github.com/ARASHz4/Advanced_Downloader

@ARASHz4

Well thanks, but I think you know better where you call which method/function whith which parameters.

Its hard to read through a whole project without any documentation

ARASHz4

@the_ class for download is downloader.cpp & downloader.h

@ARASHz4

Digging through your files i found this

QUrl Url;

        if(!DownloadListUrl[currentDownload].contains("http://"))
        {
            Url = "http://" + DownloadListUrl[currentDownload];
        }
        else
        {
            Url = DownloadListUrl[currentDownload];
        }

        FileDownload = new Downloader(Url, this);

This is impossible to work. If you have an URL like "https://upload.wikimedia.org/wikipedia/commons/thumb/5/5d/Fibonacci_spiral.svg.png/120px-Fibonacci_spiral.svg.png"
this piece of code does not find http:// in the URL string and will prepend it so it will be "http://https://upload.wikimedia.org/wikipedia/commons/thumb/5/5d/Fibonacci_spiral.svg.png/120px-Fibonacci_spiral.svg.png" afterwards.

@the_ I fixed this bug.
