If it isn't working
Work from the per-record statuses on Settings › Domain. They tell you which of the three records is the problem, which is most of the diagnosis.
“Not found”
Section titled ““Not found””No record exists at that name, as far as Rubikc can see.
- You added it a few minutes ago. Wait. This is the normal state while DNS propagates.
- The Name / Host field is wrong. Some providers want the full name
(
www.yourstore.com), others only the prefix (www). Compare against how your other records are written. - It went in the wrong zone. If your domain has nameservers somewhere other than where you added the record, the record is real but nobody can see it. Check which nameservers your domain actually uses.
“Wrong value”
Section titled ““Wrong value””The record exists, but its value is not what it should be. Open Latest DNS probe details under the records: it shows the value Rubikc expected next to what it found, which usually makes the mistake obvious.
- Copy the value from Rubikc rather than retyping it. The TXT value in particular is long and easy to get subtly wrong.
- Check for added quotes. Some providers add them for you and some expect you to. A doubled-up quoted TXT value fails.
- Check for a trailing dot on CNAME targets. Some providers add one, some reject one.
- An old record is still there. If you had a previous value at that name, make sure you edited it rather than adding a second record beside it.
The certificate record will not validate
Section titled “The certificate record will not validate”Almost always the same cause:
If there is no stray TXT, check whether the record is proxied. It needs to be DNS only.
DNS is correct but HTTPS fails
Section titled “DNS is correct but HTTPS fails”The certificate has not been issued yet. Check SSL status on the Domain screen.
If DNS has been showing Matches for a while and SSL has not moved, confirm the certificate validation CNAME is one of the records showing Matches — it is the one that gates the certificate.
The domain works, but links and search show the old address
Section titled “The domain works, but links and search show the old address”Your storefront loads on the domain, but shared links and search results still use your Rubikc address. Set Production URL to Use your custom domain and Save. See Verify and go live.
The badge says Error
Section titled “The badge says Error”Validation failed. The reason is shown in red under the domain’s records. Fix the record it names, then choose Check.
It worked, and then stopped
Section titled “It worked, and then stopped”Usually one of two things:
- A DNS record was removed. The certificate validation CNAME is the one people delete, because it looks like leftover setup. Certificates renew periodically, so removing it breaks things weeks or months later rather than immediately. Check all three records are still present.
- Your DNS moved. Changing provider or nameservers means the records need recreating in the new place.
Still stuck
Section titled “Still stuck”Note which of the three records is failing and what status it shows, then get in touch. That is far quicker to act on than “my domain does not work”.
