Github: Failed to connect to github.com:443; No error

I have been swearing for a while to realize that the git client (http://msysgit.github.com/) requires a proxy settings to be able to contact github.
Here are all the commands (don't tell me git is intuitive.... it's a hell of a lot of work only to get the basic done).
The command is "git config --global http.proxy http://proxyuser:proxypwd@proxy.server.com:8080"
All the git config settings are documented here

$ git config --global user.name "vernetto"

$ git config --global user.email pvernetto@gmail.com

$ mkdir kitammuort

$ cd kitammuort/

$ git init
