Today I get an email from LetsEncrypt.org saying my SSL certification was about to expire that I depoyed on my Nextcloud server. I look at the cert info and it sure is! So its was time for me to figure out how to renew it. I can not believe how easy it was!!
Literally one command:
sudo letsencrypt renew
You will get a message like this and you are done.
Processing /etc/letsencrypt/renewal/example.com.conf The following certs are not due for renewal yet: /etc/letsencrypt/live/example.com/fullchain.pem (skipped) No renewals were attempted.
