Serving Django App with Apache 2 on Virtual Host

I am learning the Django framework and can run my first app on the development server using:

python3 manage.py runserver

However, what I really want to do is serve my app with Apache so it can be accessed from the web. My Apache Virtual Host is:

<VirtualHost *:443>
    ServerName django.example.com
    DocumentRoot /var/www/django/hello_world/mysite
    WSGIScriptAlias / /var/www/django/hello_world/mysite/mysite/wsgi.py

    Include /etc/letsencrypt/options-ssl-apache.conf
    SSLEngine On
    SSLCertificateFile /etc/letsencrypt/live/django.example.com/cert.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/django.example.com/privkey.pem
    SSLCertificateChainFile /etc/letsencrypt/live/django.example.com/chain.pem

    WSGIDaemonProcess django.sample.com processes=2 threads=15 display-name=%{GROUP} python-home=/var/www/django/hello_world/mysite/venv/lib/python3.6
    WSGIProcessGroup django.sample.com

    <directory /var/www/django/hello_world/mysite>
        AllowOverride all
        Require all granted
        Options FollowSymlinks
    </directory>
</VirtualHost>

As you can see, this is not a complicated app I'm trying to run, just the default Django start page, but I'm getting:

My settings.py file is:

I'm running Apache 2.4.6, CentOS 7. Thank you for any help.
