Hi folks,

Is anyone who have the above combination experiencing the same issue?

I have a Windows server, on which RDP is only exposed through a ZeroTier VPN. Previously, on my Macbook, I was using the old Remote Desktop app to access it without problems. Recently, when I changed to Windows App, I can no longer access the Windows server on my device.

(Windows App is the new version of MS official Remote Desktop)

How did I single out the issue was probably due to the macOS Windows App?

  • Previous setup with old Remote Desktop app encountered no issue
  • The same Macbook, when installed with Remmina (via Docker Desktop) - an alternative RDP client, was able to access the Windows server
  • My Android phone with Remote Desktop app and ZeroTier VPN client, can also access the server without issue
  • Back to Macbook, opening Wireshark to start capturing packets on the ZeroTier tunnel interface. When telnet and Remmina, I can see TCP handshake and data packets going through, but none when using Windows App

It’s possible that the new Windows App hasn’t been given authorization to look for devices on the local network as part of the new security controls in Sequoia. If you clicked through quickly after the installation it may not be enabled:

System Settings > Privacy and Security > Local Network
