Nginx always searches index.php in the wrong directory

[Issam2204]

Hello!

I have a web root directory pointing to /var/www/html.

I have several subfolders in /var/www/html where I host different projects.
Example: /var/www/html/chatserver

When I try to access http:// MYSERVER.net/chatserver I always have an error
because Nginx tries to search for the index.php in the root web folder
instead of the actual subfolder.

This is my default server:

    server {
    listen 80;
    listen [::]:80;
    server_name MYSERVER.net www.MYSERVER.net;
    return 301 https://$host$request_uri;
    }

    server {
    listen 443 ssl;
    listen [::]:443 ssl;
    server_name MYSERVER.net www.MYSERVER.net;

    }

    }

    fastcgi_param   SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
    }


Any help/ideas on how to solve this? 
Thanks for reading!
