ERROR: GitError(Code:ERROR, Class:OS, failed to send request: A connection with the server could not be established

When I try to use Pkg.add() for any repos and Pkg.init() I get the following error. I am using windows 7. I have Set the proxy settings for the firewall walk around, but nothing seems to have changed.
