Hololens 2 disconnect from node dss

Hello, I am trying to send video captured from the local camera of my computer from unity to hololens 2. I set up the environment in unity putting a local screen that shows what my local camera is capturing and a button to be pressed to start the connection.

Please I really need someone to help me.
