AEM cloud dispatcher vhost mapping with domain

Hi,

We are trying to set new domain in cloud 

Followed the documentation and domain shows verified.

In domain mapping section status is shown as deployed 

If I try access the domain with home page I am able to view it. The vhost header is resolved to publish. 

I tried adding custom vhost for newly added domain and a farm file.

My vhost is not picking up and x-vhost is always publish not the custom one.

After checking found that domain mapping section has go live button to make domain available for traffic as mentioned in the docs.

So my host file not resolved willbe causing because of domain not yet go live?

But when the status is deployed how I can access the domain.

Could someone help with the insights
