Hi,

We are trying distributed testing using JMeter but getting below errors
when we trigger the test:

Error in reconfigure method java.rmi.unmarshalException: Error unmarshaling
return header, nested exception is:
java.net.socket.exception: Connection reset

Connection refused to host 10.76.xx.xxx; nested exception is:
java.net.ConnectException: Connection refused: connect

Regards,
Deep
