Online Login requires the user to input a user account which is assigned with an online license by the license administrator. And Internet access is required, because the online license will be activated by the Appeon license server during the login process.
If you have configured a firewall on your machine, make sure you configure your firewall to allow access to the following domain used by the Appeon online license activation mechanism:
Protocol: HTTPS
Port: 443
Domain: api.appeon.com, api2.appeon.com, api.appeon.net, api2.appeon.net
