As a hosting platform we issue hundreds certificates per day. Since ACMEv2 is the default server (14.07), we hit many times a day the changed "New orders" limit There were too many requests of a given type :: Error creating new order :: too many new orders recently.
For users of the ACME v2 API you can create a maximum of 300 New Orders per account per 3 hours.
We use only one account with certbot. We never had this rate limit before this changes.
Following Rate Limits - Let's Encrypt I filled the rate limit form but after submission there is no way to know submission status and answer delay. Can you give me some informations?
If you provide information that can help identify your request (email address, ACME account ID, domain names, etc) I could see what the current status of your request is.
