Wrong warning mail? Let's Encrypt certificate expiration notice


#1

Hi,

I receive an email 12-04-2017 10:50

Your certificate (or certificates) for the names listed below will expire in
9 days (on 22 Apr 17 08:35 +0000). Please make sure to renew
your certificate before then, or visitors to your website will encounter errors.

motionscykellob.dk
www.motionscykellob.dk

But the certificate doesn’t expire before 01-07-2017

Have I misconfigured something and therefore gets the warning mails?

Best regards

Jan

You’re okay, but the email isn’t technically wrong.

This certificate expires April 22 (as do a few others):

The warning system only realizes you’ve renewed a certificate when the new certificate covers the exact same names as the old certificate. Your new certificate has added two names (for motionscykelloeb.dk), so the email doesn’t know that it’s been “renewed”. But everything’s okay.
