Server Access Exception on UWP/HoloLens

Crossposting from the Unity forum: https://forum.unity.com/threads/exception-when-launching-on-hololens.546418/

I continually get the following exception when deploying to HoloLens:

Exception thrown at 0x7771C7D2 in DCS_Demo.exe: Microsoft C++ exception: Platform::COMException ^ at memory location 0x00D9F6D0. HRESULT:0x80072EE7 The text associated with this error code could not be found. WinRT information: The server name or address could not be resolved

Here's the call stack:

> KernelBase.dll!7771c7d2() Unknown   [Frames below may be incorrect and/or missing, no symbols loaded for KernelBase.dll]   [External Code]   Vuforia.dll!57e847db() Unknown   Vuforia.dll!57e8551e() Unknown   Vuforia.dll!57e7fb3c() Unknown   Vuforia.dll!57e8395c() Unknown   Vuforia.dll!57e80531() Unknown   Vuforia.dll!57e7ff44() Unknown   Vuforia.dll!57e839fc() Unknown   Vuforia.dll!57e804a4() Unknown   Vuforia.dll!57e8294b() Unknown   Vuforia.dll!57e88f21() Unknown   Vuforia.dll!57e84817() Unknown   Vuforia.dll!57e81d48() Unknown   [External Code]

The app doesn't crash but it affects performance on my app because it's taking up a lot of time on the comm thread seemingly.

the app is not connected to the internet and as I understand it does not have to be.

So why is Vuforia constantly trying to talk to a server and how can I stop it?

Thanks!
