    Unity Version 2018.4.3 & 2019.1.11f1

    I use Holographic Emulation try to remote my Emulation.
    My connect setting like this:

    But when I clicked connect button.
    After 1~3 sec...
    I got error mesage is : "Disconnected with error ProtocolVersionMismatch"
    (And the error message looping)


    I try to remote by script.
    Like this example:
    https://docs.unity3d.com/ScriptReference/XR.WSA.HolographicRemoting.html

    It is work,
    but when I connecting success, the Hololens 2 emulation's "remoting player app" will return back home.

    I guess,this example is just for Hololens 1 not 2.

    So...
    Can anyone tell me...
    The tool Holographic Emulation connect to Hololens 2 is work?
    Maybe I just miss some step??

    I've been seeing the same problem. I think I figured it out. The Holographic Emulation window is buggy (you may have noticed you can never disconnect it once connected).

    If you close the window, then reopen it (Windows->XR->Holographic Emulation), then it seems to get unstuck. You might also have to restart Unity.

    Hello,
    I have also an issue trying to use Holographic Emulation on Unity 2019.2.6f1 with HoloLens 2.
    I have installed the Windows Mixed Reality package 3.0.6
    When I try to connect Unity crashes and in Unity log file I found this error :
    "attempt to access an invalid address"

    I experienced the same issue.

    After some workaround, my solution was to make sure I was using the same Wi-fi network as the Hololens 2 used. Any Ethernet connection between devices will disturb the connection.

    Changing Scripting backend from .Net also can be a game changer.

    Thought I had this problem as the disconnect button was grayed out. Then I realized that I didn't have WSA Holographic Remoting Supported in the XR Settings. Once I enabled that I can connect and disconnect no problem.
