Last updated: Jul 16, 2024 1 minute read.

Description

A user may find that they are unable to update a CNAME from within the Dashboard. The following error will appear in a pop-up:

There was a problem updating your CNAME, please contact support

Cause

The UI for setting the domain name has a very strict validation, so it may just be rejecting this domain.

Solution

The best way to set the domain is to use the Tyk Dashboard Admin API, to obtain the organization object via a GET request and then update the object using a PUT request with the relevant CNAME added to the body of the request.^[1] Restarting the process will then set the domain.
