I got an Email telling me that I need to upgrade to ACMEc2.
I have installed the latest certbot on the Server, following the instructions from https://certbot.eff.org/lets-encrypt/ubuntuxenial-other
In my renwal file of the domain:
version = 0.31.0
server = https://acme-v02.api.letsencrypt.org/directory
I have the latest certbot version provided by the ppa installed (see https://launchpad.net/~certbot/+archive/ubuntu/certbot) and the “server” as well as the “account” point to an actual v2 account and server URL.
Does someone has a hint what the problem could be?
