Using Ubuntu 20.04, Nginx, Gunicorn, and Django. Can't get domain to work.

I followed the tutorial here and seemed to have everything working: https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-20-04

The IP works fine, no errors with nginx, no errors with gunicorn, but my domain just won’t work.

Sites available:

server {
    listen 80;
    server_name tabletopadmiral.com www.tabletopadmiral.com 167.99.5.101;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /home/andrewi/tta;
    }

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

gunicorn.service:

[Unit]
Description=gunicorn daemon
Requires=gunicorn.socket
After=network.target

[Service]
User=andrewi
Group=www-data
WorkingDirectory=/home/andrewi/tta
ExecStart=/home/andrewi/tta/tta/bin/gunicorn \
          --access-logfile - \
          --workers 3 \
          --bind unix:/run/gunicorn.sock \
          tta.wsgi:application

[Install]
WantedBy=multi-user.target

gunicorn.socket:

[Unit]
Description=gunicorn socket

[Socket]
ListenStream=/run/gunicorn.sock

[Install]
WantedBy=sockets.target

Any help would be appreciated.
