You receive the “Account Creation Status: failed” error message while adding a domain from WHM >> Account Functions >> “Create a New Account” option which states that there is no free IP address to assign to your new domain.
The package you are using while adding a domain has the “Dedicated IP” option enabled which searches for a free IP on the server and tries to assign to the every new domain you create. To overcome the issue, you will have to deselect the “Dedicated IP” option from the package which can be achieved via ssh.

Save the file. You should now be able to create an account from WHM successfully.
