403 Forbidden nginx/1.6.3 (centos 7)

After i installed nginx/1.6.3 & php56w-fpm, i run my website in the browser with a VH listening for port 80 and it worked, but at the moment I wanted to create a VH that listens for port 443 to access via https and that's when I get error 403 Forbidden, when I go to the error log what it shows me is *1 directory index of "/var/www/PROJECT/web/" is forbidden. I set 777 to www folder and i change the owner to nginx:nginx and the same error still comes out. The configuration of my VH is as follows

server {
listen 443 ssl spdy;
server_name project.lh;
root /var/www/PROJECT/web;

server_tokens off;

ssl on;
ssl_certificate /etc/nginx/ssl/cert.crt;
ssl_certificate_key /etc/nginx/ssl/cert.key;

ssl_session_timeout 5m;
ssl_session_cache shared:SSL:20m;

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers HIGH:!aNULL:!MD5;
ssl_prefer_server_ciphers on;

location / {
try_files $uri $uri/ /app.php$is_args$args;
}
# PROD
location ~ ^/app\.php(/|$) {
fastcgi_pass 127.0.0.1:9000;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
fastcgi_param DOCUMENT_ROOT $realpath_root;
internal;
}

location ~ /\.ht {
deny all;
}

location ~ \.php$ {
return 404;
}

error_log /var/log/nginx/project-ssl_error.log;
access_log /var/log/nginx/project-ssl_access.log;
}

My site is made in symfony 2.8.
Could you please help me to explain how should i check? Thanks

 

Do you have index.php or index.html file in the '/var/www/PROJECT/web/' directory?

You should add the following directive in your configuration:

index index.htm index.html index.php;

Code (markup):

 

There should be default index file, such as index.php or index.html etc, if you're using a index file different than usual, you need to specify the default index file in confirguration like @RoseHosting said.
