I am unable to renew my certs because I’m hitting a rate limit: "Error creating new registration :: too many registrations for this IP: ". It seems somebody on my web host is spamming requests so that I can’t get a renewal.
But why are renewals subject to the registrations-per-IP limit? Should’t a valid renewal always go through? Or is my renewal script implemented improperly? I’m using this script: https://github.com/will-in-wi/letsencrypt-webfaction
I made an issue to the Github page of the script, but didn’t find a solution: https://github.com/will-in-wi/letsencrypt-webfaction/issues/122 The developer says: “We have to register a new private key before we can issue a cert with it. That’s why it is running an additional registration call.”
