Obtaining an SSL Certificate in Ubuntu

Help
1

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: moodlevirtue.tk

I ran this command: sudo certbot --apche

It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator apache, Installer apache

Which names would you like to activate HTTPS for?

1: moodlevirtue.tk

You have to add an A and/or AAAA record pointing to your server's IP addresses in your DNS control panel.

There isn't one currently. If you added it, it might be that freenom DNS are slow. You might think to change them. (I don't know if you can, on their free plan)

FYI: When using HTTP authentication, the IP must be reachable via the Internet.
[RFC 1918 prohibits routing such numbers via the Internet]

Name:    www.moodlevirtue.tk
Address: 10.0.2.15

Furthermore, when providing links/access to your site, Internet users must reach you via a routable IP.
