Sub folder not found

I m using cakephp 2. I have install it on AWS and nginx server. the site is working perfectly. but I wants to access sub folder but its deny . So please help me.
Here is my sub folder URL.

Already changes .htaccess but its failed to access the sub folder .
sub folder name is "m1"
Below the .htaccess code

RewriteEngine on RewriteBase /m1/ RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]

Please review the .htaccess code and help me.


I think the m1 subfolder would have to be in webroot to be accessed like that. Is it there? Can you provide the absolute path for your subfolder?
