2. Adjust Settings: If needed, modify your settings, such as switching to HTTP, by using subcommands. For example, help to view help documentation or exit to close the connection.

3. Check Connection: If the VPN window opens, navigate through its options. Use help to get additional information.

4. Use Quoted Addresses: Remember to enclose the IP address and port in double quotes for secure connections.

5. Consider Other Services: If using a different VPN service, follow its specific command syntax.

This process allows you to connect and manage your VPN session effectively from the command line.
