Can I activate Nucleo Pro if the machine is behind a firewall?
Just below the Activate menu item is an “HTTP Proxy” menu item. If your web browser uses an HTTP Proxy to connect to the Internet you will need to enter the correct settings in that dialog and enable the settings. Activation will then use those settings to connect to our activation server. You can check for proxy server settings by looking in your web browser’s settings or your system’s Internet control panel (Windows) or Network System Preferences (Macintosh). Ask your Internet Service Provider (ISP) or local network administrator for more details.
