I installed Letsencrypt Certificates for my website end of July 2020, I believe. Looking into a comment line of the generated cerificates it says:
## Your cert will expire on 2020-10-20. 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"
Examining the certificate with a browser by accessing the website, it says that it is valid until Dec, 19th, 2020.
Another thing I'm wondering about is that files and directories in /etc/letsencrypt
are carrying timestamps of Sept 21. I don't recall to have them touched in that time.
My web server is (include version): apache2
The operating system my web server runs on is (include version): Ubuntu 18.04.5
I can login to a root shell on my machine (yes or no, or I don't know): yes
I'm using a control panel to manage my site (no, or provide the name and version of the control panel): n
The version of my client is (e.g. output of
certbot --version or
certbot-auto --version if you're using Certbot):
