CodeIgniter routing not working under Nginx - php

Question

Ubuntu 16.04 setup by referencing this and this.
I'm able to see my welcome to CI page on http://x.x.x.x/index.php, but when I add a test controller and go to http://x.x.x.x/index.php/test I get a 404 response. I'm also not using a domain but rather just the IP.
/etc/nginx/nginx.conf:
user www-data;
worker_processes auto;
pid /run/nginx.pid;
events {
worker_connections 768;
}
http {

/etc/nginx/sites-available/default:
server {
listen 80 default_server;
listen [::]:80 default_server;
root /var/www/html/codeigniter;
# Add index.php to the list if you are using PHP
index index.html index.htm index.nginx-debian.html index.php;
server_name x.x.x.x;
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ =404;
}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/run/php/php7.0-fpm.sock;
}
}
/var/www/html/codeigniter/application/config/config.php:
$config['base_url'] = ''; //tried putting http://x.x.x.x
$config['index_page'] = 'index.php';
$config['uri_protocol'] = 'REQUEST_URI';
Tried creating a test controller:
<?php
class Test extends CI_Controller
{
public function index()
{
echo "Hello World!";
}
}
?>
But it doesn't load and I get a 404 response.
Any ideas?

changing
try_files $uri $uri/ =404;
to:
try_files $uri $uri/ /index.php;
Not really sure why this fixes things, but found it by trial and error referencing:

Here's a bit on try_files:
