I have a Tobii Pro Spectrum eyetracker. https://www.tobiipro.com/product-listing/tobii-pro-spectrum/
It is supported by the Tobii Pro SDK  https://www.tobiipro.com/product-listing/tobii-pro-sdk/#Specifications

I am using Inquisit Lab 5, and have a license for the Tobii plugin.
If I do
<eyetracker>
/plugin = "tobii"
</eyetracker>

and try to run a study, it fails with two errors for element eyetracker:
Tobii Eyetracker Error 30: 'Search for eye trackers on the network timed out.' [function connect]
Initialization of eye tracker failed.

If I then click on the Output tab, it says the same two lines and then:
Inquisit Error: Line 2168, File Script.cpp.

I can access the eyetracker through Tobii Pro Eye Tracker Manager, and through that I can use "Track status" to get the IR leds to turn on and track my eyes.
Alternatively, I can turn on iMotions 6.4 and it will connect to the eyetracker and track my gaze point.  So I know the eyetracker is working, but Inquisit's Tobii plugin is failing to connect.

Do you know why?
