Answer 1

It is possible that you are using a proxy to get the ssl content, but your proxy setup is wrong. You should consider using http as proxy scheme, and then https as your scheme for the actual content. This solved my problem.

Answer 2

As the error message says, the probability is that the peer is talking plaintext, not SSL.

Answer 3

I have gotten this error before when my connection was being blocked by complex firewall rules. If you have in place it might be worth looking at the configuration.
