It should print out what is going wrong or at least fail faster.

What version of python are you running? Is your server using a self-signed cert? It's hard to know exactly what part is causing the handshake to fail, but we could definitely add a configurable timeout option.

Had the same issue. Turns out that I had to configure proxy on my machine to reach our STS portal.
