Hi,

You don't need the g version, use the latest one of that OpenSSL series.

[emircanacardev]

i already try latest version of openssl but i got same output

x.pro file

LIBS += -LC:\Qt\Tools\OpenSSL-Win64\lib\VC\x64\MTd -llibcrypto -llibssl
INCLUDEPATH += C:\Qt\Tools\OpenSSL-Win64\include

when i try to include .h like #include <openssl/aes.h> it is not give error for header file but i am getting this error:

false "OpenSSL 1.1.1g  21 Apr 2020" ""
qt.network.ssl: QSslSocket::connectToHostEncrypted: TLS initialization failed

There's no use trying to use OpenSSL v3 with Qt 5.15.2 as it was not available at this time. As I wrote, use the latest version of the series that is mentioned in the message.

Even better: use a more recent version of Qt which supports OpenSSL v3.

Thanks for your time.
I tried Opensslv3 (i installed in Qt Maintool) didnt work.
I tried openssl latest version from (OpenSSL) and i tried other version in this site but didnt work.
I cannot use qt latest version because of my company is using qt 5.15.2.

OpenSSL v3 is not compatible with 1.1 hence you cannot just dump it there and use it.

Please note that 1.1 has reached end of life so you should really consider updating your setup for security reasons.

Yes you are right. I am not getting error but

YouTubeAPI::YouTubeAPI(QObject *parent)
    : QObject(parent)
{
    connect(&manager, &QNetworkAccessManager::finished, this, &YouTubeAPI::onResult);
}

void YouTubeAPI::onResult(QNetworkReply *reply)
{
    qDebug() << "replied";
}

the onResult function didnt called i guess, i can not see the replied message as a output.

in linux it is work with qt5.15.2, i can see the replied message as a output but i have another problem with linux that the web engine not work in there.

how can i solve properly this problem in windows and qt 5.15.2?

i am new in qt and i am getting so different errors :/

You should start by connecting the error related signals. That should provide more information about what is going on.
