I just started using letsencrypt on Ubuntu 16.04. Recently I started to receive emails from letsencrypt notifying me that my certificate is about to expire from it’s 90-day limited run. I have everything setup to automatically renew it. However, I accidentally clicked the “unsubscribe” link in the email and I guess now I won’t be getting those helpful emails. I would like to re-subscribe but since I didn’t use certbot for install, the method outlined on the website will not work for me.
Does anyone know how I can re-subscribe to the expiration notice emails?
