LEMP on Ubuntu 14.04 Connection Timeout

Any help would be appreciated. I’ve been at this for 2-3 days now (really only my second time setting up any kind of server). I did the one click install for LEMP with DigitalOcean. At some point I reinstalled nginx and reinstalled php, to fix issues I had made. Now I am at a point where everything works fine when I use only an index.html file in my /var/www/example.com/public_html directory. However, when I attempt to use my project files (built on PrestaShop), i go to my domain, it is redirected to http://192.168.33.10/, and eventually gets a connection time out with no further error code/log that I know of. Without getting too much into config specifics (since everything is loading when I only use a plain index.html) does anyone have any idea as to what could be causing this? Does it sound like a memory limit issue… if so how could I verify that? I also have a mysql database already set up… but I would think if it was a mysql error I would get more of an error log. Will be happy to give any more info as needed
