Hi! I'm using Appwrite Cloud Sites with Cloudflare for SaaS for multi-tenant custom domains.

Problem:

Custom domain: donate.pekeetong.my → CNAME to sites.donorcare.my → sgp.cloud.appwrite.io

Browser: Shows "Not Secure" ❌

How do I whitelist custom domains when SSL is managed by Cloudflare for SaaS?

TL;DR
**Summary:** Developers are experiencing a Fastly SSL error when using custom domains with Cloudflare for SaaS, specifically in the context of Appwrite Cloud Sites for multi-tenant custom domains. **Solution:** To whitelist custom domains when SSL is managed by Cloudflare for SaaS, ensure that the SSL certificate is properly configured and that the custom domain's CNAME settings point to the correct destination.
