    I have api-key: 63YUZ8NP5SW1D302

      Make sure you have OpenSSL installed

      I have api-key: 63YUZ8NP5SW1D302
      How can I use the key?

        OpenSSL

        This link is nothing about OpenSSL.
        OpenSSL need to connect to the project?

          Qt uses OpenSSL to implement TLS and SSL

            I installed everything in MaintenanceTool. Do I need to download additional OpenSSL?
            If you need to install OpenSSL, then how to connect it to Qt?

              Hi,

              What OS are you on ? My guess would be Windows.

                    downloaded openssl-1.1.1b and put it in the folder with the executable file. Did not help.
                    In openssl-1.1.1b there is no libeay32.dll.

                              Then try again with the latest version of the 1.0 series.

                                I downloaded openssl-1.0.2r. There is no bin folder. No .exe files. No libeay32.dll. What to do with it?

                                        Did you check whether you can connect to another https resource and if it triggers the same error ?

                                          Not check. I don't know what other resource to connect to.
