WHMCS - TCAdmin | Curl error: URL rejected: No host part in the URL Url: http://:/Aspx/billingapi.aspx

I have been searching everywhere for an answer to this and everything is many many years old and irrelevant or just does not work.
So I do have my Server fields filled out for the TCAdmin 2 Advanced (MVC) server addition and for hostname and IP address it is the same contents (IP Address)

 

When attempting to make a demo order / module automation I get the following error:
"Curl error: URL rejected: No host part in the URL Url: http://:/Aspx/billingapi.aspx"
