Let's Encrypt renewal stuck on civilbot.ai — rate-limited after *.civilbot.ai DNS-01 failure

My production cert for civilbot.ai expired on Jun 22 and automatic renewal has been failing. The site is currently serving an expired cert and showing NET::ERR_CERT_COMMON_NAME_INVALID to all visitors. Could you investigate and re-trigger provisioning on your side?

Site details

  • Site: civilbot.netlify.app
  • Team / site slug: [fill in]
  • Primary custom domain: civilbot.ai
  • DNS: managed by Netlify DNS (zone hosted with you)
  • Currently issued (expired) cert domains: *.civilbot.net, civilbot.ai, civilbot.net
  • Created: Jan 24 · Updated: Mar 24 · Expired: Jun 22

Errors observed (in order)

  1. First error on the HTTPS panel:

    SniCertificate::CertificateValidationError: Unable to verify challenge for *.civilbot.ai:
    

    DNS problem: NXDOMAIN looking up TXT for _acme-challenge.civilbot.ai - check that a DNS record exists for this domain

    This is unexpected — civilbot.ai is on Netlify DNS, so Netlify should be writing the _acme-challenge TXT record automatically. It appears that wasn’t happening.

  2. After a hard refresh and removing the civilbot.net domain alias, the error changed to:

    SSL Provisioning is temporarily disabled because too many recent CertOrder creation with the site.
    

    So provisioning is now throttled.

Things I’ve tried

  • Hard-refreshed the HTTPS panel
  • Removed civilbot.net from domain aliases to shrink the cert request
  • Confirmed Netlify DNS is managing the civilbot.ai zone

What I’m asking for

  • Lift the rate-limit / throttle on cert provisioning for this site so renewal can be retried.
  • Investigate why the _acme-challenge.civilbot.ai TXT record wasn’t being written automatically given the zone is on Netlify DNS — so the next renewal cycle doesn’t fail the same way.
  • Confirm whether the *.civilbot.ai wildcard is being added to the cert request automatically (it wasn’t on the original Jan 24 cert) and whether I should opt out of that if I’m not using wildcard subdomains.

Thanks — happy to share screenshots or grant team access if useful.
