FIX BY SYMPTOM

Custom domain not working?

A custom domain usually fails for one of four reasons: the DNS records do not exactly match what your host asks for, conflicting A or AAAA records remain, a Cloudflare proxy blocks the host from issuing SSL, or only the apex (or only www) was added. Once the domain loads, update auth redirect URLs, OAuth origins and webhook URLs, or login breaks next. VibePitstop fixes domain cut-overs as fixed-price deploy fixes.

DNS checklist

  1. Copy the records from your host exactly: typically an A record for the apex and a CNAME for www, plus any verification TXT record.
  2. Remove old A records and any AAAA records on the same name.
  3. Many registrars do not allow a CNAME at the apex; use the A record the host gives you (or Cloudflare's CNAME flattening if the host supports it).
  4. If DNS is on Cloudflare and the host issues its own certificate, set the record to DNS only (grey cloud) unless the host documents proxy support.
  5. Add both the apex and www in the host, and pick one to redirect to the other.
  6. If you have CAA records, allow the host's certificate authority.
  7. Allow time for propagation (often minutes, up to 48 hours), then re-verify in the host.

FAQ

Why is my custom domain stuck on "verifying"?

The records do not match exactly, conflicting A or AAAA records remain, the verification TXT record is missing, or DNS has not propagated yet.

Why did login break after I added my domain?

Auth providers only redirect to allowed URLs. Add the new domain to Supabase redirect URLs and OAuth origins.

Can you connect my domain for me?

Yes, as a deploy fix: $400–800 fixed, quoted after the $149 diagnosis. You keep the domain and DNS in your own accounts.
