Hololens- Failed to Connect to Device

I realize this question was asked elsewhere, but the answers seem to direct towards the paring process between Hololens and a PC, which is part of my problem.

I made an app in Unity and exported to Visual Studio. When I try to run it on the Hololens, I get this error:

Error DEP6957 : Failed to connect to device using Universal Authentication. Please verify the correct remote authentication mode is specified in the project debug settings.

I understand that the first time you run, you should be prompted to pair both the PC and the device, but I never got this request, and I have no field to input the Hololens PIN that is found on the Settings app. I tried both with the USB cable and by WIFI, following instructions from: https://developer.microsoft.com/EN-US/WINDOWS/HOLOGRAPHIC/holograms_100, but with no success.

Is there anything that I can do to debug, and succeed in trying my app on the Hololens?

P.S. I am running visual studio on Windows 8, and I can't download the emulator because it seems that I'm lacking Hyper-V. Hope this helps.

Thanks.

If after the update to windows 10 the problem still happens, here is a simple way to solve it.

First I was running applications in the Hololens already when suddenly I got the error message described in the original question.

So, I went to the Project Properties. The Debug Tab. There there is the "Remote Machine" space. My Hololens was selected there. But I pressed the [Find] Button and in the window that appeared I selected my hololens (it was on). Alternatively you could put the Hololens IP address there. Put Ok and voila! it works as before

I was in a similar situation recently. I don’t have the pro windows 10 version therefore no Hyper-V. However i was able to establish the connection Using the Hololens App from the Windows store, after connecting i created a new user and then i was able to pair using Wifi and USB

Building for Hololens requires UWP. To build UWP app for Unity these requirements must be met:

  • Unity 5.2 or later
  • A Windows 10 machine
  • Visual Studio 2015 RTM, (the minimum version is 14.0.23107.0). Please note that earlier versions, for example Visual Studio RC, are not supported in Unity 5.2.
  • You’ll also need to install the Windows 10 SDK.

Like you mentioned, you are using Windows 8 but Windows 10 is required. You can read more bout this on Unity blog.
