title: why is remote holographic player on HoloLens2 stuck in "receiving" mode?
body: <p>I developed a Unity (Version:2020.3.16f1) project that is &quot;streamed&quot; to a HL2 via Holographic Remoting Player (v2.7.4.0) when in play-mode (openXR is used).
  It all worked fine until yesterday morning when I started the play-mode. Since then the Holographic Player on the HL2 is stuck in &quot;Receiving...&quot; eventhough the scene on the laptop is running. I downgraded the HL2 firmware to august 2021 already - didnt help. Does not work either using Wifi nor USBC for connection.</p>
  <p>Did anyone ever have this problem ?</p>
