Hi
In the latest Cygwin 2.2.1. git doesn’t work with proxy authentication.
The git version is 2.5.1 and the curl version is 7.43.
The error prints fatal: unable to access
'https://github.com/mockito/mockito.git/': Unknown SSL protocol error
in connection to github.com:443
In my previous Cygwin 1.7.35 (with curl 7.41) this problem didn’t
exist. Git for windows (git 2.5.1 version, but curl is 7.44) seems to
work too.
I assume that there is a bug in curl rather than in git.
