We are a large hosting provider and use let's encrypt SSL for the client domain. We have allowed clients themselves to issue, renew the certificate by the use of certbot. Sometimes, we got a rate limit on retry failure or on issuing a new certificate. How can we manage
a) rate limits on issuing new certificates?
b) rate limits on renewing the certificate?
c) retry failure limits?
check the docs for rate limit
and the integration guide.
