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: misterprotocol.photos
I ran this command: certbot certonly
It produced this output: The usual

I can login to a root shell on my machine (yes or no, or I don't know): Yes

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): None
I'm not running a web server. I'm using Let's Encrypt certs to encrypt an FTPS server in FileZilla Server. Why? Because I'm using Sony and Canon cameras to send pictures back to my FTP server, I want to use encryption, and the cameras have support for FTPS and that's all.
To do this, you have to install root certificates on the cameras. Some sort of problem with FileZilla Server prevents me from just generating and using my own root cert and certificate, so I decided to use Let's Encrypt, since FileZilla Server has support for generating and using a Let's Encrypt certificate. However, at least on my Canon camera, when I downloaded what I assumed to be the correct root cert for my freshly-generated certificate, and tried to load it into the camera, the camera said "This root certificate may be expired", and refused to load it. Sure enough, printing out the root cert shows a "Not After" date of last September. How do I fix this?
