    Then that is your issue, Qt 5.15.2 supports OpenSSL 1.1

      @SGaist So does that mean that I need to upgrade to Qt 6?

        No, it's not required although advised. You can get OpenSSL 1.1 and use it with 5.15.2.

          @SGaist Can you please help me to solve the same issue in my case

          Im using qt5.15.2 and when I try to print the sslversion its "OpenSSL 1.1.1g"

          When i try to command the openssl version in my machine its "OpenSSL 1.1.1q "

          So here it means my machine needs to match with "OpenSSL 1.1.1g" or below than that right ?

          If so can you please give me a link of downloading openssl 1.1.1g exe file

            @keksi-venksi What do you get if you put:

            qDebug() << QSslSocket::supportsSsl() << QSslSocket::sslLibraryBuildVersionString() << QSslSocket::sslLibraryVersionString();
            in your code ?

            Changing the patch version should not be a problem to load OpenSSL.
            Where did you install it ?

              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

                That's because the dlls cannot be found at run time hence the empty "Loaded Version".

                Go to the Run part of the Project panel and add the path to were the dlls are to the PATH environment variable.

                  @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

                  image.png

                  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.

                              @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.

                                  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

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

                                      @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.
