jhipster ssl ubuntu apache2 setup - spring-boot

Question

I have generated my app using Jhipster. Configured it to run on amazon ec2 with Ubuntu 16.x and apache with following configuration and godaddy a record. When I hit the website url it maps and renders the site without any issues.
apache2 configuration
<VirtualHost *:80>
ServerName 111.22.33.444
ProxyPreserveHost On
ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass / http://111.22.33.444:8080/
ProxyPassReverse / http://111.22.33.444:8080/
</VirtualHost>
Nest step, trying to configure SSL. I have bought the SSL from godaddy for my domain, configured it and uploaded the *.crt files into /etc/apache2/ssl. I quickly realized just by adding another virtual host configuration for port 443 will not work because JHipster app is running on 8080. I went back and looked at https://www.jhipster.tech/production/ and they have instructions for configuring SSL with HTTPS configuration with a front-end proxy and this where I got lost and am unable to configure SSL and serve up my domain on https.
What is not clear is can I still run the app on 8080 and simply follow the instructions under HTTPS configuration with a front-end proxy? First, I configured apache using "lets encrypt" using the following command
sudo certbot --apache -d doamin.com --agree-tos -m info#domain.com --redirect
it failed saying
Failed redirect for domain.com
Unable to set enhancement redirect for domain.com
It didn't work.
What are the changes for Jhipster application that I need to do? Should it run on 443 or continue to run 8080 and update virtual host configuration? How should i configure virtual host?
I have searched high and low with no instructions. Any direction is much appreciated.

Assuming your app is available at http://127.0.0.1:8080/, you can successfully configure Apache for HTTPS with Certbot by following the below steps.
Setup server with:
sudo apt-get update
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:certbot/certbot
sudo apt-get update
sudo apt-get install python-certbot-apache apache2
Start with the config:
<VirtualHost *:80>
ServerName example.com
ServerAlias example.com
ProxyPass / http://127.0.0.1:8080/
ProxyPassReverse / http://127.0.0.1:8080/
ProxyPreserveHost On
ProxyRequests Off
</VirtualHost>
Enable plugins and restart Apache2, making the app accessible at the domain configured above:
a2enmod headers proxy proxy_http
service apache2 restart
Then run certbot with the instructions in the docs:
sudo certbot --apache -d example.com
After that, your app will be accessible at the domain you configured and served via HTTPS.
