    @SGaist Which dll's ? openSSL one

    I have added this "C:\Qt\Qt5.15\Tools\OpenSSLv3\Win_x64\bin" one into path in both environmental variables and in project run's build environment as well

    but dlls name's have an extra point that it has version name in it as libcrypto-3-x64.dll libssl-3-x64.dll

        Hi, one other thing you can try is to build and run the "Secure Socket Client Example" in Qt's examples. (it's included both in Qt 5.14 and 5.15.) Make sure you run in it Release mode (not Debug).
        If that example works, then maybe you can copy the files from it...

          @keksi-venksi Here it is, since you are using Qt5.15.2, according to the Qt source code (https://code.qt.io/cgit/qt/qtbase.git/tree/src/network/ssl/qsslsocket_openssl_symbols.cpp?h=v5.15.2#n683)

              tryToLoadOpenSslWin32Library(QLatin1String("libssl-1_1" QT_SSL_SUFFIX),
                                           QLatin1String("libcrypto-1_1" QT_SSL_SUFFIX), result);
          

          It will only find v1.1.x of openssl.

            That example itself not working in my qt 5.14.2

                @keksi-venksi This is Qt's internal source code, you are not supposed to use it. I post it to show that it is hard coded to load openssl v1.1.x only.

                  @keksi-venksi why did you install OpenSSL v3 since you need v1.1 ?

                    @SGaist

                    if (QSslSocket::supportsSsl()) {
                    qDebug() << "SSL is supported.";
                    } else {
                    qDebug() << "SSL is not supported.";
                    qDebug() << "Build Version:" << QSslSocket::sslLibraryBuildVersionString();
                    qDebug() << "Loaded Version:" << QSslSocket::sslLibraryVersionString();
                    }

                    The above code returned a value of
                    SSL is not supported.
                    Build Version: "OpenSSL 1.1.1d 10 Sep 2019"
                    Loaded Version:
                    ""

                    Im using both qt 5.14.2 and qt5.15.2

                    If i print it in Qt5.14.2 the open ssl version is OpenSSL 1.1.1d
                    If i print it in Qt5.15.2 the open ssl version is OpenSSL 1.1.1g

                    My cmd output it
                    openssl version
                    OpenSSL 1.1.1q 5 Jul 2022

                    I installed in the C folder "C:\Qt\Qt5.15\5.15.2"

                    Also I would like to puts some debugging notes

                    When I use HTTPS:somelink , the reply is TLS initialization failed.
                    but when I use HTTP:somelink the reply is fine

                    @keksi-venksi you need to download openssl 1.1.1 on windows.
                    When done , copy libssl-1_1-x64.dll and libcrypto-1_1-x64.dll in your qt installation folder, mine is
                    C:\Qt\Qt5.13.2\5.13.2\mingw73_64\bin
                    After that it will work

                        @Bonnie I have not factored that into account but in the absolute, if not provided by the installer I would go get the official libraries.
