Vive XR Elite doesn't recognize my PC for Wi-Fi casting

[EM-SIG]

Hi, I can't cast my Vive XR Elite on my PC : my headset does not recognize my PC when trying to cast with WiFi.

 

Here's le step I have followed to configure the connection :

• My PC and my Vive XR Elite are connected on the same WiFi
• I use my smartphone (OnePlus 7 Pro) to connect both PC and headset on WiFi, in the same room
• The WiFi connection is set on Private
• I have a 5 Ghz WiFi connection
• Vive Business Streaming is installed on both PC and headset
• I have tried to disable the fire wall on my PC

 

Weird fact : I'm able to connect to my PC with SteamVR thanks to Vive Business Streaming, but I want to access to my Vive apps (because I would like to launch APK files installed on my Vive XR Elite) so SteamVR is not an option to me.

 

Do you have any recommandation to help me ?
