I don't remember exactly when I registered the certificate, but the domain was created 2016-02-10.
When I ran the following command:
letsencrypt/letsencrypt-auto -d unixtalk.chat
it allowed me to create a certificate, but warned me that I was updating the certificate well before it needed to be renewed, and somewhere in there I think it advised me that such early certificate renewals would be throttled.
So...
When should I be renewing certificates obtained through Let's Encrypt?
Thanks,
