The following errors were reported by the server:
Your account credentials have been saved in your Certbot
configuration directory at /etc/letsencrypt. You should make a
secure backup of this folder now. This configuration directory will
also contain certificates and private keys obtained by Certbot so
making regular backups of this folder is ideal.

Hi all and Let’s encrypt,
Thanks for this free and wonderful service, am a complete noob at this SSL installation and followed this tutorial to install an SSL certificate for my website: Configuring Let’s Encrypt SSL Cert for Nginx on Ubuntu 18.04
I believe I was meant to only install it for my main domain and not sub-domains, I am assuming that the sub-domains would automatically have been secured by HTTPS if I only installed it for the my main domain, is this correct?
Regardless, I added 2 of my sub-domains to be encrypted too and thus resulting in the errors above. I did not receive any successful message of the SSL certificates being installed.
As the message states, the certificates are stored on my dedicated server now.
Question: How do I delete the SSL certificates for the two sub-domains, do I need to or they can be just left there? For cleanliness, would prefer to remove/uninstall them.
Question: How do I continue to install the certificate for my main domain which am guessing will secure all the sub-domains I add also. Do I need to run the installation again or otherwise?
Please help and would appreciate any advice to help resolve this.
Thanking you very much in advance, your help is much appreciated.
