It works for me like this:
Code:

Note: moving to "origin/origin" which isn't a local branch
If you want to create a new branch from this checkout, you may do so
(now or later) by using -b with the checkout command again. Example:
git checkout -b <new_branch_name>
HEAD is now at 4b1c0b4... UPDATE : paypal force on ssl port 443
