Very new to hosting a server and this is my first time to get a SSL cert.
While I'm following the guide in the Certbot website, this error popped in.
I have no skill for server managing so please bear with me.
The log is right below.
My domain is: sonfoundry.duckdns.org
I ran this command:
sudo certbot --nginx -v
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator nginx, Installer nginx
Which names would you like to activate HTTPS for?
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
1: sonfoundry.duckdns.org

Certbot failed to authenticate some domains (authenticator: nginx). The Certificate Authority reported these problems:
Domain: sonfoundry.duckdns.org
Type: connection
Detail: IP Address: Fetching http://sonfoundry.duckdns.org/.well-known/acme-challenge/bNxR42bsdQ-vkC8zlJah6utxoPXigk6L7NEQEYI6YD0: Error getting validation data
Hint: The Certificate Authority failed to verify the temporary nginx configuration changes made by Certbot. Ensure the listed domains point to this nginx server and that it is accessible from the internet.
Cleaning up challenges
Some challenges have failed.
Ask for help or search for solutions at https://community.letsencrypt.org. See the logfile /var/log/letsencrypt/letsencrypt.log or re-run Certbot with -v for more details.
