CloudXR server not working on HP men laptop (4070 laptop GPU)

Need your help in one more thing. For checking if we can stream from SteamVR, do I have to run SteamVR on a different “client” machine or can I run it on the server itself? Im talking about this step: Unofficial Debug Guides 1: Does my CloudXR server even work?

I have linked the exact step of the guide in the above url.

Also, you mentioned that hmd should not be connected to SteamVR, but unless I do that SteamVR gives error : “Headset not detected, please make sure headset is connected properly, then reset it below”.

And I also get this error window:

Please help
