If a connection cannot be made, handle the netStatus event before you create a NetStream object or any other objects. You may need to retry connecting to the server's URI, ask the user to reenter a user name or password, or take some other action.

The event codes to watch for and sample actions to take are as follows:

Write client code to handle netStatus events

  Create a NetConnection object and connect to the server. Then, write a netStatus event handler in which you detect each event and handle it appropriately for your application, for example:

public function netStatusHandler(event:NetStatusEvent):void
{
    trace("connected is: " + nc.connected );
    trace("event.info.level: " + event.info.level);
    trace("event.info.code: " + event.info.code);
    switch (event.info.code)
    {
         ...
         case "NetConnection.Connect.Rejected":
            trace ("Oops! the connection was rejected");
            // try to connect again
            break;
         case "NetConnection.Connect.Failed":
            trace("The server may be down or unreachable");
            break;
         case "NetConnection.Connect.AppShutDown":
            trace("The application is shutting down");
            // this method disconnects all stream objects
            nc.close();
            break;
        ...
    }
}
