java rmi remote-method-invocation networking Java

I recently switched to I'm currently working with an scenario with my RMI (Remote Method Invocation) server implemented in Java 11. The server works well when clients connect and call methods, but after a client disconnects (either normally or due to a network scenario), the server fails to accept new connections from that client again. I have set up my RMI service like this: ```java public class RMIServer { public static void main(String[] args) throws RemoteException { try { MyRemoteObject obj = new MyRemoteObject(); Naming.rebind("//localhost/MyService", obj); System.out.println("RMI Server is running...); } catch (Exception e) { e.printStackTrace(); } } } ``` On the client-side, I have the following code to connect: ```java public class RMIClient { public static void main(String[] args) { try { MyRemoteService service = (MyRemoteService) Naming.lookup("//localhost/MyService"); // Call remote methods } catch (Exception e) { e.printStackTrace(); } } } ``` After testing, when the client disconnects abruptly (for example, if I terminate the application), and then I try to reconnect, I encounter a `java.rmi.ConnectException: Connection refused to host` behavior. I tried implementing a reconnection logic in the client, but it still fails after the first disconnection. I've also checked the `rmiregistry` and confirmed that it's still running. I suspect it might have to do with how the server handles connections or the way I'm managing the remote object lifecycle. I would appreciate any insights into how to ensure that clients can reconnect properly after disconnection, or if there's a specific configuration I might be missing. I'm on Linux using the latest version of Java. Is there a better approach?
