[SOLVED] Function custom domains never get the ssl certificate issued

I am on v1.4.13 self host. The appwrite server is installed on https//backend.atomtalkpvtltd.com and auto generated function domain is https://658e6c1bbb67ee011c8a.backend.atomtalkpvtltd.com/. I want to use https://verify.atomtalkpvtltd.com/ and the CNAME points to https://backend.atomtalkpvtltd.com/ but the ssl is not generated for verify domain. On tapping retry link, I get the following message:

TypeScript


Generation failed

In order to continue, set the following record on your DNS provider. DNS records may take up to 48 hours to propagate. Please retry over the next 48 hours, but if verification still fails, please contact support.

Failed to rename certificate cert.pem. Let's Encrypt log: Saving debug log to /var/log/letsencrypt/letsencrypt.log

I can access the function without using https though.

Any help is appreciated.

TL;DR

The user is experiencing an issue with SSL certificate generation for custom domains in their appwrite server. They are on version 1.4.13 and trying to use the domain https://verify.atomtalkpvtltd.com/. The CNAME points to https://backend.atomtalkpvtltd.com/, but the SSL certificate is not generated for the verify domain. They receive an error message when trying to retry the certificate generation. They can access the function without using HTTPS. No solution is provided in the thread.
