Getting 429 rate limit on domain with less than 20 certs in past week

This is for domain

Based on, we’re not seeing that we are definitely below the rate limit on certs issued for that domain -

However, we’re getting a 429 error when we are attempting to issue a cert for a subdomain on using letsencrypt-express v2.0.5 :

2018-08-07 00:11 +00:00: { type: 'urn:acme:error:rateLimited',
  detail: 'Error creating new cert :: too many certificates already issued for: see',
  status: 429 } 

Any ideas? has been backlogged recently. It probably has an incomplete picture of certificates issued in the last week.

Google’s CT search site should be more up-to-the-minute but it’s harder to work with:;include_subdomains:true;;issuer_uid:4428624498008853827&lu=cert_search

Thanks mnordhoff, I’ll work with that instead and see if I can figure out where these certs are issued from

Also, universities can often get a Let’s Encrypt rate limit increase relatively easily, so you might also want to get in touch to request that the rate limit be increased.
