How to properly set the path in nginx?

Question

Nginx

On the server there is such a path to the script /var/www/example/sites/example.com/parser
There is this in nginx.conf

location /parser/ {
    root /var/www/example/sites/example.com;
}

When trying to access example.com/parser/ it  returns 403 Forbidden
What else needs to be added here to make it work fine?

Answer 1

see error_log there it will be written why 403, maybe there are no rights.
