Hi,
I have never worked on 1-click DO ghost droplet. But I worked on issues related to Let’s Encrypt certificates a few times. So, let’s try to solve your problem…

1. SSH to your droplet with root user or the user who can obtain root privileges with sudo command (so called sudoer).

ssh root@your_droplet_domain_or_ip

2. Execute undermentioned command which should show us your current certificates, their expiry dates, and installation paths. Provide us this info, please. You can hide your domain name if you do not want to share it.

sudo certbot certificates

Hello, Santry1304. You’re really remarkable, you know that? English is not your 1st language, you’re unfamiliar w/the command line, & you’re trying to tackle it all anyway. Congrats to you! So–please don’t apologize for anything!

While Ghost is your cms, what we’re really concerned about here is what is your webserver? That would generally be Apache or Nginx, but you might use another such as Litespeed. We also need your domain. If you could tell us that, I’m sure someone will be able to let you know the commands to use to get LetsEncrypt to renew the cert & to automate it. Who knows? It might even be me! :)
