[modules/RTC/BridgeChannel.js] <WebSocket.e.onclose>: Channel closed: 1006

hi guys,
Although I can get media from JVB, can not get active speaker icon and blue layout.

I get 2 errors:
1)failed: Error during WebSocket handshake: Unexpected response code: 200
2)[modules/RTC/BridgeChannel.js] <WebSocket.e.onclose>: Channel closed: 1006

any idea?
thanks.
