SSL handshake failed on Mac, the same code works fine on Windows

Hi, I’m using Qt 5.3.1 installed via online installers both for Windows (8.1 ×64) and MacOS (10.9.4). When I try to load into a QWebView just any site via http*s* protocol I’m getting ‘SSL handshake failed’. Exactly the same code works fine on Windows. Any hints what’s wrong on Mac? Should I build Qt from sources with openssl-linked option or it’s already built with it? thanks
