Generating HTTPS Certificate using DNS a Challenge through Let's Encrypt
I have a Raspberry-Pi running a Flask app through Gunicorn (Ubuntu 20.04 LTS). I am exposing it to the internet using DuckDNS.
Dependencies
sudo apt update && sudo apt install certbot -y
 
Get the Certificate
sudo certbot certonly --manual --preferred-challenges dns-01 --email senpai@email.com -d mydomain.duckdns.org
 
After you accept that you are okay with you IP address being logged, it will prompt you with updating your dns record. You need to create a new TXT record in the DNS settings for your domain.
For DuckDNS users it is as simple as entering this URL in their browser:
http://duckdns.org/update?domains=mydomain&token=duckdnstoken&txt=certbotdnstxt
 
Where mydomain is your DuckDNS domain, duckdnstoken is your DuckDNS Token ( Found on the dashboard when you login) and certbotdnstxt is the TXT record value given by the prompt.
You can check if the TXT records have been updated by using the dig command:
dig navanspi.duckdns.org TXT
