Nginx keeps answering with the ‘default nginx site’ despite it being removed from config

I was hoping someone could help me with this strange problem. On a 'clean' server install, I have the following "website.com" and nginx configs, yet if you try to go to the http version of www.website.com, it renders the default nginx page, instead of forwarding over to the https version like it's configured to do. The site is using the AWS Linux ami, and is behind an elb (hence the directive for elb-check).

In my /sites-available (and ln -s'd to /sites-enabled), all I have (even when doing a # ls -lah) is:
default_server website.com elb-check

The configs (as well as the nginx.conf are below).

Thank you in advance! Please let me know if there's additional info/configs you need.

website.com:
