After the series of steps taken to connect to the master server, join a room, play a game, then leave the room, the master server connection may have been disconnected although the client has never called the Disconnect Master Server function. If you call the Is Master Server Connected function, it returns false.
This is normal behavior.
The connection to the master server is automatically disconnected if the client sends no request for a certain period of time, and it is automatically reconnected when the client sends the next request. The Is Master Server Connected function returns false when Disconnect Master Server is used to disconnect or when the SDK automatically disconnects on its own.
This automatic disconnection-reconnection cycle doesn’t affect the behavior of functions that communicate with the master server. You don’t need to check the connection status using Is Master Server Connected before accessing the master server.
