I want to use QNetworkAccessManager to access a page via https, but when I try it I get the following output:

qt.network.ssl: QSslSocket: cannot resolve CRYPTO_num_locks

qt.network.ssl: QSslSocket: cannot call unresolved function SSLeay  
qt.network.ssl: QSslSocket: cannot call unresolved function  SSLeay_version

I'm using arch x86_64 and QT 5.9.

After typed in a terminal: openssl version -v I got
OpenSSL 1.1.0f 25 May 2017, so it's the newest.

I added to main.cpp also:

qDebug() << "SSL version use for build "
         << QSslSocket::sslLibraryBuildVersionString();
qDebug() <<"SSL version use for run-time "
         << QSslSocket::sslLibraryVersionNumber();

and I got the following: 

SSL version use for build:  "OpenSSL 1.0.1e-fips 11 Feb 2013"
SSL version use for run-time:  0

Do you have any suggestions what can I do it to resolve this issue ?

Check the version of OpenSSL installed on your host

QNetworkAccessManager tries to find the functions in the lib which is loaded at runtime.

Most probably you have old version of OpenSSL installed.

Also check this thread on Qt vs OpenSSL compile-time/run-time dependencies
