If you're seeing PORT _ ERROR on Windows, it's likely that the driver did not get installed correctly for some reason. To fix this, navigate to
, C:\ProgramData\ZeroTier\One\tap-windows\x64
then right click on the file zttap300.inf
and select "Install" from the menu.
Note: The folder C:\ProgramData
is hidden by default and requires Administrator privileges to access.
If you have other VPN or similar apps that require network drivers, you may want to try uninstalling them, probably rebooting, and reinstalling ZeroTier.
