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!).

Thanks.

Hi @soheil_paper, I am not sure I’m tracking with all the steps you’ve taken nor the end goal. But, I can offer some general advice.

First, the domain vip42.ir shows as active on Cloudflare and the name servers point to cloudflare.

Next, the suspended error pages are not cloudflare errors.

Finally, do you have/can you share documentation that you’re following from painting-persta to set up the domain?
