403 Forbidden - Nginx

I set my nginx.conf to my /home because PHPStorm was not editing a file inside /usr/share/nginx/html. However, I have a new problem. When I access a URL via folder it returns a 403 Forbidden But when I access a specific file in the URL, Nginx manages to run the code in PHP. Is there any way I can resolve this? When nginx.conf was in the previous configuration, this was not the case. This is the current content of my nginx.conf:

worker_processes  1;

events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    types_hash_max_size 4096;

    server {
        listen       80;
        server_name  localhost;

        location / {
            root   /home/erierfcasi/www/;
            index  index.php index.html index.htm;
            autoindex on;
            autoindex_exact_size on;
        }

        location ~* \.php$ {
            fastcgi_index  index.php;
            fastcgi_pass   127.0.0.1:9000;
            include        /etc/nginx/fastcgi_params;
              fastcgi_param  SCRIPT_FILENAME  /home/erierfcasi/www/$fastcgi_script_name;
        }
    }
}
