HoloLens stopped doing network discovery suddenly

Today one of my HoloLens just stopped doing network discovery out of the blue. The OnReceivedBroadcast event is never called. The other HoloLens have no problems receiving broadcast signals and connecting to the Host. I am using discovery code that is very similar to Holotoolkit's SharingWithUnet example.

Any clues on what I can do to troubleshoot or what might have changed?

    Doing a system reset fixed the issue

    Hey, @psi.

    How can I give you multiple up-votes? You saved me.

    For others in struggle. Apparently after HoloLens update some networks settings need to be reset. Not sure if network alone can be reset but a full reset solved it for me. Go to Settings ->Update&Security -> Reset -> Reset Device.

  • For those still struggling with NetworkDiscovery on the HoloLens, make sure you've enabled the Internet (Client & Server) capability either in Player Settings -> Publishing Settings or the Visual Studio project's manifest file.

    Seems like simply restarting the HoloLens (holding power button until "Goodbye" shows up and then holding again until "Hello" shows up) does the trick too on top of system reset.
