    Did you check that you have everything from the right architecture ?

      when i check ssl version of qt with QSslSocket::sslLibraryBuildVersionString() it say "OpenSSL 1.1.1d 10 Sep 2019"
      its mean i need to build version 1.1.1d?

        i build openssl version 1.1.1d too
        and add lib to my project
        but still no luck
        here my code and error
        2ac46222-1eee-42a2-a011-3421031a792c-image.png

        and also openssl part in pro file

        win32: LIBS += -LD:/build/ver-1d-openssl/lib/ -lcrypto
        win32: LIBS += -LD:/build/ver-1d-openssl/lib/ -lssl
        
        INCLUDEPATH += D:/build/ver-1d-openssl/include
        DEPENDPATH += D:/build/ver-1d-openssl/include
        

        edit: when i add openssl dll in debug folder of my project its work just fine
        but i need static

          Your application does not link to OpenSSL nor does Qt by default.

          As for when running your application, the dlls must be findable. The usual way is to copy the files in the same folder as your application or modify the PATH environment variable in the Run part of the Project panel.

            @SGaist yes by adding dll in exe folder im able to post data
            but there is anyway to include openssl static?

              Not without building Qt by yourself as normal Qt builds load OpenSSL libs at runtime.

                @jsulm can anyone tell me i need to pass what in ./configure to build qt with openssl statically
                i use this for build qt static for now

                configure -opensource -confirm-license -static -platform win32-g++ -optimize-size -opengl desktop -prefix "C:\Qt\static" -skip webengine -nomake tests -nomake examples -qt-zlib -qt-libjpeg -qt-libpng -qt-freetype -qt-pcre -qt-harfbuzz -qt-tiff

                i need to add what to build qt static + openssl?

                edit: i see this page in wiki
                based of this page i need to build qt like this

                OPENSSL_LIBS='-L/d/build/ssl/lib -lssl -lcrypto' && configure -opensource -confirm-license -static -platform win32-g++ -openssl-linked -optimize-size -opengl desktop -prefix "C:\Qt\static" -skip webengine -nomake tests -nomake examples -qt-zlib -qt-libjpeg -qt-libpng -qt-freetype -qt-pcre -qt-harfbuzz -qt-tiff

                in this configure OPENSSL_LIBS is Location of openssl-1.1.1g i compiled before (with mingw)

                its all ok?

                  OPENSSL_LIBS='-L/d/build/ssl/lib -lssl -lcrypto

                  This looks like linking against shared OpenSSL libs.

                    @jsulm you say i do not need to set OPENSSL_LIBS?
                    and by the way i think this 2 lib use for shared version libssl.dll.a & libcrypto.dll.a

                    and also i use mingw to build openssl and Qt

                      You don't need to rebuild Qt. Just select OpenSSL in the installer, and do what is suggested here:

                          Then the question is: Does OpenSSL need to be static, too?

                          If you can live with using OpenSSL dlls while using static Qt, you can just add the following to your configure line (also with OpenSSL from the installer) and you're done.
                          e.g. for x86 builds:

                          -openssl -I C:\Qt\Tools\OpenSSL\Win_x86\include -L C:\Qt\Tools\OpenSSL\Win_x86\lib

                              Yes. Think about it: when linking against dlls, the linker only links the OpenSSL function calls in a way that they call the dll. When linking against static OpenSSL, the linker copies the called functions' code into the executable being built.

                              Anyhow, I never did a static build of OpenSSL, so I'm not sure if the line above works for static builds, too.
