My own domain does not work

Reviewed on 4 October 2026
On this page

If your own domain does not get activated or stops working, your store stays on onbio.es while you sort it out. Find here what the Domain tab of your store says and follow the steps of that cause.

The CNAME record does not appear

How to recognise it

The domain stays in Waiting for DNS or moves to Error with «We can't find the CNAME record.», and you receive the email «We could not activate» with your domain.

Where to check it

You see it in Domain, the tab of Store, under the status of the domain.

What to do

Check at your provider that the record has the exact Type, Name and Value the screen gives, without the domain repeated in the name. Then select Try again.

Another service already uses the domain

How to recognise it

The domain moves to Error with «Another service already uses this domain on its network.»

Where to check it

You see it in Domain, the tab of Store, in the reason of the error.

What to do

Remove the domain from the other service where you connected it before, such as another store platform or a website. Once you have removed it, select Try again.

The certificate could not be validated

How to recognise it

The domain moves to Error with «We could not validate the certificate.» or with a notice that the validation took too long.

Where to check it

You see it in Domain, the tab of Store, in the reason of the error.

What to do

Check that the CNAME points to the Value the screen shows and that you have no other record with the same name. Then select Try again.

The domain has stopped pointing to your store

How to recognise it

You received the email «… has stopped pointing to your store» and the screen says «The CNAME record no longer points to OnBio.»

Where to check it

You see it in Domain, the tab of Store, in the notice about the domain.

What to do

Create the CNAME record again at your provider with the details on the screen. While it is missing, the store is served on onbio.es and the certificate does not renew. If it ends up expiring, select Try again when the record is back.

OnBio's provider failed

How to recognise it

The domain moves to Error with «Our provider failed to set up the domain.»

Where to check it

You see it in Domain, the tab of Store, in the reason of the error.

What to do

Wait a few minutes and select Try again. If it fails again, write to OnBio from OnBio support with the domain.
