Your next steps

1. Confirm which address you are connecting: your website, a workspace page, or an email sender domain.
2. Read the exact DNS instructions provided by that service. Do not copy records from an unrelated setup.
3. Compare record names and values in your DNS provider with those instructions.
4. Allow for the DNS update and certificate setup indicated by the service, then check again.
5. If it still fails, send support the domain, the affected page, the error message, and a redacted screenshot.
