ZeroTier Status - PORT_ERROR


On system Tray Icon > Right-click ZeroTier icon > Show Network

Status: Port ERROR

The solution 

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 


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. 

Or refer to these images for action taken.

if Window Security pop up, click "install this driver software anyway" to continue
