    Description

      Not sure it is completely QtC related bug: could be Qt installation package or build issue under Linux. Help->System information shows:

      Network: SSL is not supported.

      When building 4.6.1 from sources with custom QtC plugin which connects over network by HTTPS (SSL) protocol (connection) over network

      networkManager->post(request, data)

      I get same errors as above:

qt.network.ssl: Incompatible version of OpenSSL
Error creating SSL context ()

      Injected some diagnostics into my code:

      qDebug() << "SslSupport: " << QSslSocket::supportsSsl();
qDebug() << "SslLibraryBuildVersion: " << QSslSocket::sslLibraryBuildVersionString();
qDebug() << "SslLibraryRuntimeVersion: " << QSslSocket::sslLibraryVersionString();

      Which prints following output:

      SslSupport:  false
SslLibraryBuildVersion:  "OpenSSL 1.0.2k-fips  26 Jan 2017"
SslLibraryRuntimeVersion:  ""

      Under Linux I have installed openssl libraries versions: 1.0.2n and 1.1.0h including development packages. Latest one is primary on the system, can't remove. I tried to install exact version QtC was built with - 1.0.2k-fips - same result and errors as well.

      On Mac my code and the plugin works just fine, SSL connection establishes successfully. Think need to deploy somehow proper openssl library version with QtC and/or Qt online installer or allow it to load libraries available in Linux system.
