Acme client not updating keys automatically

[David Mehler]

Hello,

I've got a Freebsd 10.3 system running several ssl-enabled web
servers. I've got letsencrypt keys for all of them. I'm using
py27-certbot (am not stuck on it so if there's an alternative), and
have a cron job set to check keys and update them by doing a certbot
renew.

I thought something was wrong when I kept getting key expirey notices
from letsencrypt, then I checked a site and got a key has expired
message.

Suggestions welcome.

Thanks.
Dave.
