Cannot handle connection ready

Hi

I have tried to run the example

(fedml-pip) PS C:\Temp\FedML\python\examples\simulation\mpi_torch_fedavg_attack_mnist_lr_example> python torch_fedavg_defense_mnist_lr_one_line_example.py --cf config/fedml_config.yaml

However, I got the message and stop running
```

[FedML-Server(0) @device-id-0] [Tue, 06 Jun 2023 12:22:30] [INFO] [fedml_comm_manager.py:37:receive_message] communication backend is alive (loop_forever, sender 0 to receiver 0)
