Need information for proxy server non-authentication when activation

I'd like to make my proxy server non-authentication from  PCs to DraftSight's activation server.

The proxy server does allow access to DraftSight when activation if I set user name/password.

So, I can do the first time activation because there is a "Edit Proxy Setting" button and the setting menu.

But, when in re-activation, there is no "Edit Proxy Setting" button. And I can't reactivate.

 

Therefore, I need information for making the proxy server non-authentication;

-IP Adress

-Port

-URL ,etc..

 

I  tested with

-Windows7 SP1 32bit

-DraftSight 2015 SP1
