Set up Django, Nginx and Ubuntu 18.04 - "welcome to nginx" landing page displays when www. prefix is loaded with domain. Works fine without.

Hello,

Warning - Complete newbie here.

I’ve followed the below guide “How To Set Up Django with Postgres, Nginx, and Gunicorn on Ubuntu 18.04” to set up my Django website.

https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-18-04

Everything works fine when i search for my website via “website.com”, however when i search for “www.website.com” i get a welcome to nginx landing page.

I’ve attempted to fix this by adding the “www.” prefix version of my domain to the server_name line in my server block as per below.

server {
    listen 80;
    server_name website.com www.website.com;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /home/peter/websitedirectory;
    }

    location / {
        include proxy_params;
        proxy_pass http://unix:/run/gunicorn.sock;
    }
}

However when running sudo nginx - t on the above, i get a warning:

nginx: [warn] conflicting server name: “www.website.com” on 0.0.0.0:443, ignored

I’m not entirely sure what this means. I feel like this should be relatively simple to fix, can anyone help? Thanks!
