simplescripts API

Im trying to get simplescripts to communicate with cpanel accounts on my server

the current settings in simple scripts show the url to return to cpanel FROM simplescripts to be

https://USER_IP:2082/?domain=USER_DOMAIN&pass=USER_CPPASS

but using this method does not work on my server

it shows

https://myserveripaddress:2082/?domain=domain.com&pass=cpanelpassword

This webpage is not available
Google Chrome could not load the webpage because "myserverip" took too long to respond. The website may be down, or you may be experiencing issues with your Internet connection.

where can i find on cpanel a list of allowable urls to go directly to cpanel by typing into the browser address bar?



in simplescripts it shows

USER_IP, USER_DOMAIN, USER_UNIQUE, USER_USERNAME, USER_PASSWORD, USER_CPHOST, USER_CPUSER, USER_CPPASS, USER_CPREFER, USER_EMAIL
For Example: https://USER_IP:2082/?domain=USER_DOMAIN&pass=USER_CPPASS

would a setting within whm cause it not to connect in this manner?

also how can i make it so when i goto http://domain.com/cpanel

that it pops up a window to enter user/pass and not take me to cpanel login html webpage?

thanks
