We’re using LE extensively for certing client sites, and now we’re receiving expiration warning notification emails for a number of domains that seems to be in error.
Here is the email:
Your certificate (or certificates) for the names listed below will expire in 4 days (on 08 Aug 16 20:38 +0000). Please make sure to renew your certificate before then, or visitors to your website will encounter errors.
But I’ve verified the certificates, and they do not expire until October 18th.
Could it be a bug on your side, Lets Encrypt?
