OK, good. You are nearly there.

Are you certain that /var/www/direct is correct, on my system I
use /var/www/html/direct.

Does the user running the web server have read access to
the /var/www/direct/0/0/0/0/0/ directories? Find out which user runs the
apache process (normally apache, www-data or nobody) then try accessing
the file as this user, e.g.

# sudo -u apache ls -l /var/www/direct/0/0/0/0/0/
