If you have trouble cloning/pushing on [e-mail] right now, you could use these config[1] for ~/.ssh/config

    Host github.com
      Hostname ssh.github.com
      Port 443

Cloning and pushing to github now works in my machine.

Wow! Huge thanks, this actually works (for those of you still having trouble)
