Thanks, is the code below what you’re after?

Just as a test, yesterday i also removed all reference to website.com and www.website.com placing a dummy domain under server_name in /etc/nginx/sites-available/website. I restarted nginx and tested my website.com and www.website.com domain. Everything was still the same (website.com leads to django landing page, www.website.com leads to “welcome to nginx” landing page. This seems unusual?

/etc/nginx/sites-available/website:

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

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

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

}
server {
    if ($host = website.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    listen 80;
    server_name website.com;
