[SOLVED] Adding custom domain stuck at "Certificate is being generated ..."

I tried multiple times, it always like this. (I added another custom domain, different subdomain with this one, it worked within 20 mins)
Could anyone help?
echo | openssl s_client -servername [my domain] -connect [my domain]:443 2>/dev/null | openssl x509 -noout -issuer -subject -ext subjectAltName
issuer=C=US, O=Certainly, CN=Certainly Intermediate R1
subject=CN=t.sni-820-default.ssl.fastly.net
X509v3 Subject Alternative Name:
DNS:t.sni-820-default.ssl.fastly.net

Adding custom domain, verification success, but stuck at "Certificate is being generated ..."

I can help! The issue is that your custom domain is still pointing to Fastly's default certificate instead of your custom one. The certificate generation appears to be stuck or failing.
A few questions:
What service are you using (Fastly, Cloudflare, AWS, etc.)?
Did you verify the DNS records are correctly pointing to your provider?
Are there any error messages in the full certificate logs beyond what's shown?

it would help if you shared what domain you're trying to get the certificate for

@Joshua @Steven , thank you for following up this thread, the support team helped me fixed this by adding the "CNAME for _acme-challenge.mydomain".
Question: After everything works, could I delete this "CNAME for _acme-challenge.mydomain" in my DNS records?

best to leave it

@Steven
I have the same issue, I did added appwrite NS records and my domain is verified.

Can you share me the acme challenge CNAME details, I will try adding it

Hey, it would be great if you can create a separate support thread along with the domain details.
