I have issue form tomorrow, my agent is not dispatch to some room. this fixed automatically after mid day now, I'm getting same issue

Do you have a specific session ID where agent did not get dispatched. This is most likely insufficient agent's available to handle current load or concurrency.

here is session ids :*RM_AaxtTCUWYQ3M*,RM_RgrSkVRFo5Ry,RM_HAo72sWzmpHG,RM_dcDyNGLQvgFn,RM_PihFCt5FcdJh,RM_QbKnQybGorK9,RM_yHYzdvJu5Zma sometimes agent connects without participant my agent id : A_irhtWgMuJDhF

RM_3U6K29eq2iNH

and

RM_AaxtTCUWYQ3M

used the same room name. You should use a unique room name each time. I think that will help resolve the issue you are seeing
