# Domain and certificate problems

Verification stuck, certificate warnings, and wrong-site symptoms.

## In brief

- **Audience:** Builders
- **First check:** The DNS record, character for character

Nine domain problems out of ten are the DNS record: wrong host, wrong target, or an old conflicting record on the same name. Start there before anything else.

## Checklist

1. Compare the record at your DNS provider to what the console shows, character for character.
2. Delete any pre-existing A or CNAME record on the same hostname — conflicts silently win.
3. Allow for propagation: minutes usually, up to 48 hours worst case.
4. Re-run **Verify** in the console after fixing.

## Certificate warnings

Certificates issue automatically after verification passes. A browser warning during setup means propagation isn't done; a warning appearing on a previously working domain means the DNS record changed — check whether someone edited it.
