[CLOSED] Why custom domain not working - verification failed

I have asked AI to suggest running terminal commands to check my current setup for the my custom domain - api.mydomainname.com - at Appwrite Cloud

Here is the comment / feedback from the AI analysis:

Perfect! The global DNS propagation check confirms all DNS servers worldwide see your CAA records correctly, including certainly.com.nslookup+1
Summary of Global DNS Results
✅ Google DNS (8.8.8.8): Shows certainly.com and sgp.cloud.appwrite.io
✅ Cloudflare DNS (1.1.1.1): Shows certainly.com and sgp.cloud.appwrite.io
✅ Quad9 DNS (9.9.9.9): Shows certainly.com and sgp.cloud.appwrite.io

All three major global DNS providers return the same results, confirming:

CAA record includes 0 issue "certainly.com" ✅

CNAME points to sgp.cloud.appwrite.io ✅

DNS is fully propagated worldwide ✅

Final Diagnostic Report for Appwrite Support
You now have complete evidence that this is a Fastly/Certainly backend issue.

SSL Certificate Analysis
OpenSSL Connection Test Results:

Current certificate being served:

Subject: CN=t.sni-820-default.ssl.fastly.net
Issuer: C=US, O=Certainly, CN=Certainly Intermediate R1
Valid: Nov 3 16:02:04 2025 GMT - Dec 3 16:02:03 2025 GMT
Problem Identified:

Fastly is serving default/fallback certificate (t.sni-820-default.ssl.fastly.net)

Certificate is NOT for api.mydomainname.com

Certainly IS the CA (correct), but certificate issuance failed despite valid CAA

Can you please assist - the issue i think is quite similar to https://discord.com/channels/564160730845151244/1395340182810787840
which require manual intervention from your side and contacting Fastly...

What's the domain?

if you have a support ticket, you can continue with that. there's no need to post here for this because the community cannot help you

[CLOSED] Why custom domain not working - verification failed

They will reply there. It's monday, they don't work during the weekend (except emergencies) 😅

thanks for the heads up @D5 ; it was rather unfortunate that the problem occurred near the weekend ; so no premium weekend support?

You can purchase a higher support plan if you wish. See https://appwrite.io/docs/advanced/platform/support-sla

thanks, because the pace i think is a bit slow, get reply on a biz day, reply back, got another reply the following biz day (while the issue is still not being resolved)... and so on

There's a link to a contact form at the bottom of the linked page so you can inquire about a support plan

ok thanks @Steven

just curious, if i did not submit for support, you technically can help me with the issue?, because the last reply that i got is

REPLY FROM SUPPORT:
Looks like there's a ownership conflict.

Could you please place the following text string, in its entirety, in the DNS TXT record for either the apex domain (jyourdomain.com) or the subdomain api.yourdomain.com to demonstrate ownership of the domain?:

fastly-domain-delegation-xxxxxxxxxxxxxxxxxxxxx

I already did that, issue not resolved (not sure if appwrite or fastly needs to be doing something on your or their end), but it's a bit sad that i need to wait for the next window / next day for a follow up respond

As mentioned, we can't help here. Reply to the support ticket

okay, because sometimes i see people got helped here (technical wise) in discord support , that's why i'm asking

They're things in self-hosting, free plan or things that don't require the intervention from core team
