I needed a certificate for my private cloud server on my LAN. It is normally an automatic thing to install and update letsencrypt certificates, however with a private server that is not on the internet one must run the commands manually every 90 days.

Your certificate and chain have been saved at /etc/letsencrypt/live/cloud.example.com/fullchain.pem. Your cert will expire on 2019-01-05. To obtain a new or tweaked version of this certificate in the future, simply run certbot again. To non-interactively renew *all* of your certificates, run "certbot renew" - If you lose your account credentials, you can recover through e-mails sent to paul@example.com. - 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. - If you like Certbot, please consider supporting our work by: Donating to ISRG / Let's Encrypt: https://letsencrypt.org/donate Donating to EFF: https://eff.org/donate-le
