I am trying to add my subdomain api.getmyself.app to my Custom Domain, but I keep getting the error: Domain 'getmyself.app' is owned by another customer
I have removed this root domain from my previous GitHub Pages, but the error persists. It seems the domain is stuck in a stale configuration on the Fastly network.
I changed nameservers from Name.com to Cloudflare, but it still wont let me add custom domain
TL;DR
Developers are facing an issue with domain verification while trying to add a subdomain. Even after changing nameservers, Fastly conflict persists due to a stale configuration. Solution: Contact Fastly support to resolve the domain ownership issue.
