Or just forgot to restart the server. When I switched my private domains
to Let's Encrypt, I assumed that I would reboot the host at least once
in 90 days (e.g., because of a new kernel), so I wouldn't have to
restart the server after obtaining a new certificate. That turned out to
be not quite true. Not only doesn't Debian issue new kernels quite as
often as I thought, the time window is quite a bit shorter: If you
obtain a new certificate every month (as I do), the certificate may be
up to 31 days old when the server is restarted, so there are only 59
days left. So it's a good idea to either restart the server immediately
after obtaining a new certificate or have some other cron job which
restarts the server regularly.
