Hi Appwrite team,

we’re using Appwrite Sites and TLS provisioning for our custom domain fails.

Domain: somnara.app

Error: Failed to create TLS subscription – max number of certificates (Fastly)

Current state:

  • Nameserver-based verification (ns1.appwrite.zone / ns2.appwrite.zone)
  • DNS resolves correctly to Fastly (151.101.3.52)
  • Fastly serves only the default SNI cert (t.sni-820-default.ssl.fastly.net)
  • Result: certificate name mismatch for somnara.app

Context:

  • Domain was previously attached to a Vercel project and has been fully removed
  • DNS and routing are correct; failure happens during TLS subscription creation

Request: Please clean up any stale Fastly/Vercel TLS subscriptions for somnara.app or increase the cert limit and reprovision TLS.

Happy to provide project ID or logs if needed. Thanks!

TL;DR
Issue with Fastly certificate limit causing TLS provisioning failure for custom domain. Although the certificate limit has been fixed, there are issues with generating the certificate. The site is currently working, but the certificate generation process appears to be stuck.

we've fixed the issue with the certificate limit. can you retry verifying again?

Verify worked but generating the certificate failed. I just hit "retry" again

It's stuck at

[19:21:27] Certificate generation started.

Yes! The site is working now. Any idea about the certificate?
