I'm setting up a LEMP stack on Google Compute Engine to run Magento 1.9. I've configured the server with PHP7/Nginx with Ubuntu 14.04. When I run the Magento setup, halfway through it redirects from downloader.php to downloader/ and I get a 403 Forbidden error.
The nginx log then says this: *323 directory index of "/usr/share/nginx/html/" is forbidden.
I've Googled around and came up with some possible solutions like this, but I've checked the www.conf and it seems to listen to php-fpm already. Any ideas on where to look for the cause?
