Thank you for the notice. It is working again. Seems as if the automatic restart of nginx after letsencrypt renewal is still not working We will look into that.
btw, I'm testing meanwhile the acme.sh script. It's just pure bash and has (besides wget/curl and openssl) no other dependencies. Also it allows to restart/reload services after successful run. https://github.com/Neilpang/acme.sh Might be worth to have a look at.
We have a feature request for that in the bugtracker already, I will take a look at it, hopefully it causes less trouble than the official letsencrypt client.
been using the official client this far as well... another thing the acme.sh has (and also other clients) is that it supports DNS auth
