UWP app network connection blocked by hololens 2 window firewall

[HaoChen10]

Hello,
my UWP app, which was installed on the HoloLens, has encountered an issue and is now unable to connect to the internet.I checked the hololens diagnostic log and it stated the following event: “Windows Defender Firewall was unable to notify the user that it blocked an application from accepting incoming connections on the network. Reason: The application is non interactive Application Path:…”. My development setup includes Unity 2018.4.11f1 and Visual Studio 2019. The capability setting in AppxManifest file is:




<uap:Capability Name=“documentsLibrary” />
<uap2:Capability Name=“spatialPerception” />



The application tested all ok in unity editor but when sideloaded to hololens it failed to establish a network connection. Does anyone has any idea why the app has been blocked by hololens firewall? Thanks

Unity does not implement AR Foundation support for HoloLens. Microsoft owns and maintains their AR Foundation provider plug-in and build tools. For any questions regarding HoloLens other than specifically the UnityEngine or UnityEditor API’s, please refer to the Microsoft Mixed Reality forums: https://techcommunity.microsoft.com/t5/mixed-reality/ct-p/MicrosoftMixedReality

Forum FAQ

Who moderates this forum? This forum is moderated by the Unity XR team, most actively by engineers who work on AR Foundation and related packages. Can I send a direct message? Unity employees will not respond to direct messages on the forums. If you have a question, please ask on the forum so that other users can benefit from your answer. Is a forum post the same thing as a bug report? No. The forums can be a great way to seek advice from the development community, but Unity does not track …

Note also that Unity 2018, 2019, and 2020 are all past their end-of-life date. The minimum supported versions of Unity and AR Foundation are currently 2021.3 and 4.2, respectively.
