404 Error Page Not Working

I have a new page, I made a custom folder, with a html 404 template and everything, I just added this:

ErrorDocument 404 /404/index.html

to my .htaccess file. I can load my 404 template page manually (And it looks great) But when I load the 404 from a 404 error, I see this. Screenshot! My 404 page: http://ift.tt/1FkORfp What could be wrong?

EDIT: When I get a 404 error from the /404/ directory (where the template is) it works.
