pick and place tutorial deploying to HoloLens2 cannot connect to ROS

[lidafei123]

Describe the bug
I am trying to deploy the pick and place tutorial to HoloLens2. Running the project in unity can connect to ROS normally to implement pick and place. After deploying the unity project to HoloLens2, the application can open normally, but cannot establish a connection with ROS. The scene displayed in HoloLens2 is consistent with the scene before playing in unity.

Screenshots
The scene displayed in HoloLens2 is consistent with the scene before playing in unity.
