Automated SSL certificate issuance for a domain is failing with a 429 Too Many Requests error during the certificate request process. As a result, new certificates cannot be issued successfully.

Environment:

  • Certbot
  • Automated SSL certificate issuance workflow
  • Public domain validation
  • Let's Encrypt certificate authority

Could you please advise how to configure and use a Certbot staging environment for testing certificate issuance without consuming production rate limits? Additionally, what logs or diagnostic information should be reviewed to confirm the cause of the 429 Too Many Requests error and validate that the staging configuration is working correctly?
