Dear Richard,

Thank you for your message. If you’d like, you can try our suggestions below.

• If there’s an error message when you try to connect with someone, please feel free to share a screenshot.
• If you’re using macOS Sequoia, see our forum thread on fixing network permissions for FarPlay.
• Turn VPN off, if used. Examples of VPNs include Proton VPN, NordVPN, Cisco AnyConnect, and GlobalProtect.
• Turn firewalls off on your computer.
• If your internet service provider offers a “public IP,” subscribe to that service. Otherwise, you’ll need to ask other people you connect to port forward. If you’d like to share your internet service provider’s name, I can check whether they offer a public IP service.

Thank you,
David Liao
