NGINX 403 Forbidden at Root - php

Question

Setting up a site on AWS Lightsail using the Linux/NGINX install from Bitnami.
The root folder (/opt/bitnami/nginx/html) contains index.html as default, everything runs just fine. However, swapping that index file out for index.php returns 403 in chrome and logs the following error...
*42 directory index of "/opt/bitnami/nginx/html/" is forbidden
Index.php is executing just <?php phpinfo(); ?>.
Index.php is accessible in the browser by pointing to its path directly (site.com/index.php)
The contents of my config file nginx.conf are unmodified and as follow...
user daemon daemon;
worker_processes auto;
error_log "/opt/bitnami/nginx/logs/error.log";
events {
use epoll;
worker_connections 1024;

}

}
the contents of the include "/opt/bitnami/nginx/conf/bitnami/bitnami.conf" are as follows...
# HTTP server
server {
listen 80;
server_name localhost;
include "/opt/bitnami/nginx/conf/bitnami/phpfastcgi.conf";
}
the contents of the include "/opt/bitnami/nginx/conf/bitnami/phpfastcgi.conf" are as follows...
location ~ \.php$ {
root html;
fastcgi_read_timeout 300;
fastcgi_pass unix:/opt/bitnami/php/var/run/www.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $request_filename;
include fastcgi_params;
}
Note: I also tried adding index index.php to the above.
Any ideas as to what might be going on here?
NOTE: Troubleshooting, i tried a stripped alternative to the nginx.config file referenced above, which resolved the 403 error but wouldn't do anything other than download the index.php file when visiting the root...

Answer 1

Resolved by updating "/opt/bitnami/nginx/conf/bitnami/phpfastcgi.conf" as follows...
location / {
root html;
index index.php;
}
location ~ \.php$ {
root html;
fastcgi_read_timeout 300;
fastcgi_pass unix:/opt/bitnami/php/var/run/www.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $request_filename;
include fastcgi_params;
}
Not my proudest moment, i'll admit.
