Error trying to create a new custom domain

Hi @soyfidelfm

Welcome to the Auth0 Community!

There are a couple of potential causes for this error message, from the the CNAME DNS Record not being published to a typo and mismatch of the exact values.

To begin with, I suggest using a tool such as Network Tools: DNS,IP,Email to check if the DNS and CNAME values exist/have been recorded and then double-check that the values entered on your Auth0 side exactly match them. If you wish to use " thekiddycloud " as mentioned, you will need to make sure that everything set up correctly and also that you are using this domain in your tenant.

More information can be found in the following documentations and topics:

Hope this helped!
