Can't get past NGINX Welcome page

I have a new site devsmkapp.com that will only load the Http (Port 80), but not my SSL (Port 443). It was built with Django and is running on a DO Ubuntu 18.04 droplet. It was configured manually with gunicorn, as in, it’s not a one-click install. But it’s still a basic setup.

        listen [::]:80 ipv6only=on;

        return 301 https://$host$request_uri;

}
server {
        # SSL configuration
        #
        listen [::]:443 ipv6only=on default_server;

My site http://devsmkapp.com loads just fine, however, it does not redirect to htpps://devsmkapp.com as I have it configured to as well as https://devsmkapp.com not getting past the “Welcome to NGINX” screen saying further configuration is required. If I run sudo nginx I get:

nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:443 failed (98: Address already in use)

nginx: [emerg] still could not bind()

I have already tried sudo fuser -k 443/tcp(also 80/tcp) with sudo service nginx restart to no avail. Any help is appreciated.
