I’m a little confused as to what you are asking. Are you:
- Using Whonix-Gateway to Torify your Windows-Whonix-Workstation and want to know why you can not connect to a site via clearnet ( i.e. not over Tor )
- Using Whonix-Gateway with Whonix-Workstation and you are not able to connect to specific sites over Tor.
Try to be as specific and as you can. The more information you give the better.
