I have bought one domain by the name of http://vip42.ir/
and I am trying to add this domain to the infinityfree account (http://painting-persta.rf.gd)

So I have tried to change the Cloudflare NS setting to desired setting as you can see below:

###The Error Message

As you can see below, I can not add domain to the :
https://cpanel.epizy.com/panel/indexpl.php?option=error

By selecting Addon Domains option, as you can see below, I get the below error:

Error Adding Domain..

Also, I have tried the Cloudflare setting and get this error, as you can see below:
enter image description here

CLOUDFLARE ERROR : We were unable to identify painting-persta.rf.gd as
a registered domain. Please ensure you are providing the root domain
and not any subdomains (e.g., example.com, not subdomain.example.com)

The domain is redirecting to this site :
enter image description here

https://ifastnet.com
Or
http://suspended-website.com/

So I want to know, I must wait until 72 hours or have to do something to fix this problem (redirecting to the http://suspended-website.com or https://ifastnet.com!).
