The "Certificates per Registered Domain" <a href='https://letsencrypt.org/docs/rate-limits/' target='_blank'>rate limit</a> has been exceeded for <b>example.com</b>. Let's Encrypt allows no more than 20 certificates to be issued per registered domain, per week.<br/>

Invalid response from https://acme-v01.api.letsencrypt.org/acme/new-cert.<br />
Rate limit of certificates that can be issued for a domain per week exceeded 20, so the certificate issue was temporary banned.
There is no way to reset or override the ban. You’ll need to wait until the rate limit expires after a week. If you issued 10 certificates on Tuesday and 10 more certificates on Friday, you’ll be able to issue again starting Tuesday. You can get a list of certificates issued for your registered domain by searching on crt.sh .
Refer to the Let's Encrypt Documentation article for more information on the Rate Limits: https://letsencrypt.org/docs/rate-limits/
