Example response
If you’re calling an API hosted on Unkey
Check the hostname. Common causes are a typo, a preview domain for a branch that no longer exists, and a custom domain the owner hasn’t finished setting up. If the owner gave you this hostname, send them the request ID.If you own this API
Unkey domains work as soon as a deployment is created. Custom domains only work once we’ve verified them. Common causes:- A custom domain is still waiting for verification, even if its DNS already points at Unkey.
- The hostname isn’t one of the deployment’s domains, or has a typo.
- The domain was removed, or the deployment it pointed at was deleted.
- The certificate for a custom domain won’t issue.
How to fix
- Check that the hostname is one of the domains listed on the deployment or .
- For a custom domain, check its verification status and the DNS records we asked for, then wait for verification to finish.
- If the hostname used to work, check whether the domain was removed or its deployment deleted.
