JavaScript API : Authentication required over HTTPS?

Hi Developers,

I'm almost done with implementing the Javascript API in our website.

When requesting a chat from a HTTPS page it requests credentials

On cancel it gives the error:This application key does not have the required privileges

While looking for this problem i found the following solution but the menu option is gone.

Exception - This application key does not have required privileges

The url i'm using is: //base.liveperson.net/hcp/html/lpChatV3.min.js

My app-key is generated using the "Javascript" option.
