After adding folder, index.html & pushing to git can't access DF. Return 404

Hello,

I am using rhcloud.com services with dreamfactory plugin. I wanted to create custom admin login and did this steps:

  1. I did checkout code from the rhcloud.com. After checkout here was one index.html file.
  2. Added admin folder and index.html file.
  3. Pushed changes to rhcloud.com.
  4. After push I can not access http://project-ramis.rhcloud.com and http://project-ramis.rhcloud.com/admin/index.html. It gives 404 Not Found (nginx/1.8.0) error.

Why did it happen?
How can I get back my dreamfactory interface?
How correctly custom admin page should added?

Thanks,
Ramis
