Bug

Custom Domain verification does not work. DNS TTL set to 1 Minute via NameCheap on a brand new domain. All DNS Settings are accurate (A and TXT).
You can check the DNS Publicly (whatismydns, etc) and it shows the correct records but Sites > Custom Domain - Pending DNS changes. May take 24h to reflect.
It’s been 48 hours.

Reproduction

Steps or a minimal example prompt:

Change URL
Delete Custom Domain
Retry
Update DNS Record

End result on the domain is "Site not found" which clearly shows ChatGPT image and that message.

Diagnostics

Exact error or screenshot:

Pending DNS changes. May take 24h to reflect.

I figured it out.

Namecheap doesn’t like when you post the entire string which includes .domain.com in the TXT records so it was failing.
