You cannot use this domain for a Trial project

Input a url to setup project, this message occurred. Tried other urls, all the same response: “You cannot use this domain for a Trial project.”

  1. Is this a format error?
  2. How am I to understand what this means?

That usually happens when the domain was already used for free traffic here or it is a free domain, 3rd level domain, redirect etc.

I think your platform does not working properly, i registered first time today. My domain is paid domain and not 3rd level domain. not redirected etc.

First time i tried to trial free for 2 hours but i have same error. Dont know how to fix.

We cannot provide further consultation without know what domain we are talking about.
