How do I connect one of my laptop's to my computer's hamachi server I'm trying to connect to my habbo retro but on the laptop it says there was an error with the VPN my computer connects to the ham?

To connect your laptop to your computer's Hamachi server, first ensure that both devices have Hamachi installed and are on the same network. On your laptop, log into Hamachi using the same account as your computer, then join the Hamachi network created on your computer. If you're encountering a VPN error, check your firewall settings to ensure Hamachi is allowed through, and verify that the Hamachi network is online and your computer is connected properly. Restart both devices if necessary to refresh the connection.
