How To Reconnect to a room in google real time muliplayer

How to reconnect to a room in Google real time muliplayer with Unity3D ?

I create a quick game multiplayer connection

 const int MinOpponents = 1, MaxOpponents = 1;
 const int GameVariant = 0;
 PlayGamesPlatform.Instance.RealTime.CreateQuickGame(MinOpponents,MaxOpponent,GameVariant,listener);

and Create With Invitation Screen

  PlayGamesPlatform.Instance.RealTime.CreateWithInvitationScreen(
  minimumOpponents,maximumOpponents,gameVariation, listener);

Connected to a room with one opponent

I dissabled my Ethernet connection of one device

 Control Panel > All Control Panel Items > Network and Sharing Center > Change Adapter Settings > Ethernet >Disable this network device

I Enabled my Ethernet connection by

 Control Panel > All Control Panel Items > Network and Sharing Center > Change Adapter Settings > Ethernet >Enable this network device

   

In my game each player's data is sending to each other .

 PlayGamesPlatform.Instance.RealTime.SendMessageToAll (true, messageToSend);

Before Ethernet disconnect it works perfect . After ethernet reconnection data is not getting to each other , but if one device left the room , following event will call.

 public void OnPeersDisconnected (string[] participantIds)
   {
       foreach (string participantID in participantIds) {
           ShowMPStatus ("Player " + participantID + " has left.");
           if (updateListener != null) {
               updateListener.PlayerLeftRoom (participantID);
           }
       }
   }

How to detect , player disconnected from net and how to reconnect to same room properly
