I am experiencing web request failures that only occur on the Meta Quest 2 VR headset.
The requests return successfully in the Editor, in Desktop builds and in regular non-VR Android builds.
I have created a Unity 2022 LTS project, based on the VR Template provided in Unity Hub, and configured it for the Quest.
The headset has been configured with developer mode and all requirements have been installed.
After connecting the headset through cable, build and deployments work fine and I can navigate the sample scene.
The issue occurs on any type of HTTP request I make through scripting.
I have tested with UnityWebRequest and .NET’s HttpClient.
UnityWebRequest returns a "Cannot resolve destination host" network error with "ConnectionError" as a message result, whereas HttpClient causes a "WebException: Error: NameResolutionFailure".
What I’ve tried:
- Using different destination hosts (my own Servers, Google images or public Json REST APIs)
- Using http or https
- Enabling a custom
AndroidManifest.xmland adding"android.permission.INTERNET" and "android.permission.ACCESS_NETWORK_STATE"to it - Ensuring the correct
Android Permissionsare requested by the app to the user prior to the web requests - Ensuring OpenXR is being used and “Meta Quest Support” is enabled
- Disabling
"Force Remove Internet Permission"underProject Settings > XR Plug-in Management > OpenXR > Meta Quest Support - Enabling
"Require"underProject Settings > Player > Other Settings > Configuration > Internet Access
I have also tried deploying the app to a different Meta Quest on a different network and the issue persists.
I’ve ran out of ideas and could use some help determining what am I doing wrong.
