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.
The operating system my web server runs on is (include version): Ubuntu Server 18.04.3
My hosting provider, if applicable, is: I am running my own server.
I can login to a root shell on my machine (yes or no, or I don’t know): No but I have sudo privilage to elevate as root.
I’m using a control panel to manage my site (no, or provide the name and version of the control panel): No.
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): certbot --version shows “certbot 0.31.0”
Once I established my first certificate, the certificate had an expiration date at the end of October. I have stated receiving expiration notices and I checked the expiration date of the certificate and it is now the end of December. So the certificate appears to have automatically updated. However, I am still receiving expiration notices.
Have I done something wrong? Have I missed a step? What do I need to do now?
So you have different certificates with different combinations of domain names.
But if you use the certificate with 5 domain names, you don't need one of the certificates with two domain names -> Letsencrypt doesn't know which certificate you use -> there is no renew -> that's the mail.
