I’m using nginx and the linuxserver/letsencrypt container found here, which has been working fine for a few months. Today, I added a new subdomain and attempted to get a new cert and I see this error:
There were too many requests of a given type :: Error creating new registration :: too many registrations for this IP: see https://letsencrypt.org/docs/rate-limits/
I have only ever used 1 email address from this IP, and this is a private IP address dedicated from my ISP (i pay for a dedicated block of IPs). My IP is 99.96.206.201
No, the account is separate from the e-mail address. The e-mail address is used only for expiration reminders, while the account is represented by an encryption key.
If it's using Certbot, it's the data in /etc/letsencrypt/accounts.
