MS WindowsServer 2012: Python request - SSL: UNKNOWN_PROTOCOL] unknown protocol

on MS Windows Server 2012, the Python script is doing https request into open github repository, see full log at

http://ift.tt/1CB2ztm

The problem is (Python 2.7.10) with Windows Server 2012 connection to https sites of github, which are open for public. On all other Windows servers (including CI testing on appveyor.com) this connection works.

Maybe this is issue related to Windows Server 2012. Any help please how to modify this line ?
