The domain does not exist.
You created a hosting account for the domain name at freehosting.com, and added some DNS records to their nameservers.
You can tell this from the screenshot in the first post. it says you have the product “Free Hosting” for the domain centralmods.com.
The interface is clearly WHMCS. So if you have the domain name, you should be able to find the option Domains in the main menu (which is a SEPARATE option - it is NOT part of the Products/Services menu). Does it say centralmods.com in Domains list? Then you have the domain. Does it not say it there, then you only have a hosting account, not a domain name.
Until the domain is registered and is pointing to those nameservers, it won’t work.
And despite your wishful thinking that anyone will give you a .com domain for free: you don’t have the domain name, so it will not work.
