X-accel-redirect serving html download page instead of file.

I have a script that uses x-accel-redirect on a nginx server to send large
files (150mb+). The script serves downloads fine as long as their is a space
in the name of the directory but not when the directory is a single word.
Anyone know why it would be doing so when the file exists and the path is

Layout: /Dir/file.exe /Dir2/file.exe /Another Dir/file.exe

If it's /Another Dir/file.exe it serves the file perfectly, however if its
/Dir/file.exe it serves the html of the download page. Anyone seen this

nginx config:
