Realtime: Disconnect status changes without reason

Hello, I've started to use C# realtime API with Unity. While debugging my wrap-up for LoadBalancingClient I often receive Disconnect in OnStatusChanged with DisconnectCause = None.

Is it ok or I should tune something up? When I connect first Disconnect always received after Authenticate operation response. So, no matter what, when I connect, I always have log like this:
