Why do I get an error 'The given domain cannot be verified. HOST_NOT_FOUND' when I add a domain under Domain Mapping?

To resolve this error, check if the domain that you want to map with a Catalyst application is already hosted live in your domain provider’s hosting site and then follow these steps:

Step 1: Create a CNAME record for your domain in your DNS configuration by adding your subdomain’s value as the Host Name/Alias/CNAME.

For example, if your domain address is “portal.zylker.com”, you must add “portal” as the Host Name/Alias/CNAME value and “catalyst.cs.zohohost.com” as the Destination/Points To value.

Add the domain name in the Catalyst console. Now the process will move to the next step -> Verify Ownership.

Step 2: Catalyst will now generate a unique hash key value for the specific mapping.

Create a new CNAME record for your domain in your DNS configuration and add the following values: hash_key.subdomain as Host Name/Alias/CNAME

For example, if the hash key generated by Catalyst is “c12to00001x11pl1234h9e33w44h6789”, and the subdomain is “portal”, you must enter the Host Name as “c12to00001x11pl1234h9e33w44h6789.portal”.

Note: Ensure that you specify the subdomain “catalyst.cs.zohohost.com” as the Destination/Points To value. The changes might take some time to reflect on the DNS server. After the changes are reflected, this will verify your ownership of the domain in Catalyst. Refer to the Domain Mappings Implementation help page for the full procedure.
