connectToHostEncrypted: TLS initialization failed

[Ana_Ichi]

I tried to make a request for a free API.
t is very simple.
And i got an error:

connectToHostEncrypted: TLS initialization failed

It's my first time doing this. I will really appriciate if you please can help me to fix it .

QNetworkAccessManager mMananger;

QUrlQuery query;
   query.addQueryItem("page", "2");

//declaracion de la URL por parte
QUrl urlPage;
urlPage.setScheme("https");
urlPage.setHost("reqres.in"); /
urlPage.setPath("/api/users");
urlPage.setQuery(query);

   QNetworkRequest mRequest;
   mRequest.setUrl(urlPage);

//almacena la respuesta
QNetworkReply * mReply= mMananger.get(mRequest);



QObject::connect(mReply,&QNetworkReply::finished,[&](){
 
    QMetaEnum metaEnum = QMetaEnum::fromType<QNetworkReply::NetworkError>();
    qDebug() << "Error" << metaEnum.valueToKey(mReply->error());

    QByteArray read =mReply->readAll();

    std::cout << "Got response:\n"
              <<read.toStdString()<<std::endl;
    mReply->close();
    mReply->deleteLater();


});```

I am using 
Qt5.15.2 
MSCV2019 de 64bits 
OS Window10

Thank you

Thank you very much for all your answers.
I took the easy way using maintenance tool.

Hi and welcome to devnet,

Did you forgot to install OpenSSL ?

[Ana_Ichi]

hi, thanks for answering, I am new in this.
How can i do that?

i follow the solution of someone else and I already tried to solve it but it is too old.
i downloaded the installer from
Web Site
and selected de option for 64 bits for developers

after that i included in the .pro file:

LIBS += -LC:/Program Files/OpenSSL-Win64/lib -lubsec

INCLUDEPATH += C:/OpenSSL-Win64/include

and then in the main file

#include <openssl/aes.h>

but still doesn´t work i looked in the folder lib and i didn´t see a file named ubsec.lib

You can get OpenSSL through Qt's installer.

You also have to make she the compiler used to build it matches the one you are using.

It's a C library, so you are safe compiler wise.

Hi @Ana_Ichi.

You can read an extensive entry here https://forum.qt.io/topic/95700/qsslsocket-tls-initialization-failed.

It seems kind of funny because there are so many answers through time. Anyway, this works for me, you can test it in Windows:

1. Install OpenSSL from Maintenance Tool.

2. Independently of your compiler, go to C:\Qt\Tools\OpenSSL\Win_x64\bin (if you have 64 bits application).

3. Copy libcrypto-1_1-x64.dll and libssl-1_1-x64.dll and paste in your release or debug application executable.

Cheers,

@Ana_Ichi said in connectToHostEncrypted: TLS initialization failed:

LIBS += -LC:/Program Files/OpenSSL-Win64/lib -lubsec

I think you will need quotes around that path.
