If you are using ufw (Uncomplicated Firewall), ensure HTTPS traffic is allowed:

   sudo nano /etc/apache2/sites-available/blog.example.com.conf

   <VirtualHost *:80>
       ServerAdmin admin@example.com
       ServerName blog.example.com
       DocumentRoot /var/www/blog.example.com

       <Directory /var/www/blog.example.com>
           Options Indexes FollowSymLinks
           AllowOverride All
           Require all granted
       </Directory>

       ErrorLog ${APACHE_LOG_DIR}/blog.example.com-error.log
       CustomLog ${APACHE_LOG_DIR}/blog.example.com-access.log combined
   </VirtualHost>

This tutorial will guide you through the process of deploying a Flask application on a VPS using Gunicorn as the WSGI server and Nginx as the reverse proxy. We will use pipreqs to manage Python dependencies and set up HTTPS using Let's Encrypt.

• A Flask application ready to be deployed.
• Access to a VPS (e.g., Ubuntu 20.04).
• A registered domain name.
• Basic knowledge of Linux command line operations.
