web hosting – Infinityfree Error Adding Domain


I have this domain setting via Cloudflare:

enter image description here

I have bought the domain form nic.ir and set its dns to brad.ns.cloudflare.com & kate.ns.cloudflare.com as you can see here:

enter image description here

This is strange because this settigs working by www.awardspace.com freehostig for setting the registred domain to the host domain, but with infinityfree.net i have some problem to do it.

and by trying to add it to my infinityfree account i found this error:

Error Adding Domain..
This could be due to already adding the domain to this or another account or, you have not changed the nameservers as required or not enough time has passed since changing the nameservers..

Remember, you need to change the nameservers on a domain via registrar control panel BEFORE adding it to your account, it may take 24~72 hours to completely update the nameservers.:

Please verify your nameservers and/or change them to:

(The nameservers are changed via your domain registrar control panel, NOT your hosting control panel.)

ns1.epizy.com
ns2.epizy.com

After changing the name-servers you may have to wait 24~72 hours prior to being able to add the domain to your account..
Once the name servers are set it may take upto 76 hours before the domain can be added here.

Name servers MUST be set before adding the domain here, if your registrar REQUIRES that you add a domain before setting the name servers then you will need to use a different domain name / registrar (or contact there support requesting they manually set the name servers). We are NOT able to add domains to the vPanel without the name servers being set firstly. If this is a requirement, please UPGRADE, on our premium hosting we do allow domain names to be added without the name servers being set. Please do NOT create a support ticket unless you have waited at least 48 hours after successfully changing name servers / adding domain. 

Also i could use parking domain setting via infinityfree as you can see here:

by this setting and adding the wordpress42.epizy.com as www2 as CNAME via cloudflare

enter image description here

but again i get this error:
