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. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
I ran this command:

I recently received an email saying
Your certificate (or certificates) for the names listed below will expire in 10 days (on 26 Sep 18 15:58 +0000). Please make sure to renew your certificate before then, or visitors to your website will encounter errors.
We recommend renewing certificates automatically when they have a third of their
total lifetime left. For Let’s Encrypt’s current 90-day certificates, that means
renewing 30 days before expiration. See
https://letsencrypt.org/docs/integration-guide/ for details.
Checking the Synology NAS I saw that the certificates didn’t expire until December. I’m confused as to why I received this email.
Even through they didn’t expire until December, I renewed them again. I got no error and the new renewal date is either the same or a few days later (I forget what the original expiration date was but it was in the same month.)
