Too many certification already issued

need help im getting this error message form duckdns { "type": "urn:ietf:params:acme:error:rateLimited", "detail": "Error finalizing order :: too many certificates already issued for exact set of domains: see", "status": 429 }

If you have been hammering the cert authority with too many requests in a short time that will happen. wait a few days and try again.

It happened to me when I was first trying to figure out how to set up certs with letsencrypt.
