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
Custom domain TLS provisioning failing for somnara.app due to Fastly certificate limit. Fastly serving default SNI cert instead. Need to clean up stale Fastly/Vercel TLS subscriptions or increase cert limit and reprovision TLS.
