hosting - How to add an addon domain to cpanel with same name but different tld?

Question

I have a cpanel account with option for unlimited add-on domains. I have added a domain, say, example.org. For this, cpanel has also created a sub-domain for main hosting domain example.main-domain.com.

Now I have purchased another domain example.com. When I try to add it through addon domains option, cpanel gives an error that subdomain example.main-domain.com already exists.

Is there a way to add the second domain in this scenario?

Answer 1

The first part of the subdomain is determined by the Subdomain or FTP Username: you set when you add the subdomain.

Cpanel auto-fills this field with the first part of the domain name but you can enter anything you like.

So when you go to add example.com Cpanel will auto-fill the Subdomain or FTP Username: to example and try to create the subdomain example.main-domain.com which already exists from when you added example.org in the same way so it will throw an error like

(XID bqnr82) A DNS entry for the domain “example.main-domain.com” already exists.

Instead when you add example.com enter any unused value into the Subdomain or FTP Username: field, such as exampledotcom and the subdomain cpannel creates will be at

exampledotcom.main-domain.com
