Hi Team,

One of the users @Raj Sookrah is making use of the pilot program"Set Up Your Sandbox Custom Domain (Pilot)" as documented in : https://help.salesforce.com/articleView?id=domain_mgmt_sandbox_custom_domains_setup.htm&type=5

As per the doc, it says that we need to setup the custom domain in production and then in 'Select sandbox in the Associated Org field.'

However, they are trying to setup custom domain directly in sandbox, by following below:

Firstly created an SSL certificate. Then created the domain and attached the certificate with the domain creation. 

Next added a custom URL for the site, lastly created the DNS.

The domain looks like: https://abc.sandbox.xyz.com and created a CNAME that points to abc.sandbox.xyz.com.00Dxxxxxxxxxx.live.siteforce.com 

Under custom URL: the status for the domain: abc.sandbox.xyz.com  is being displayed as Published. However, the redirection is not happening and the domain page does not load.

~~~~~~~~~~~

Could you please help to confirm if the above steps followed are correct or not.

If not, please help to share the exact steps to be followed to complete the custom domain setup in sandbox before moving forward for production.

Also, they are making use of domain in the format: abc.sandbox.xyz.com  - please confirm if this is a right format for domain or not.

Many Thanks
