I'm trying to do distributed tests using JMeter 5.1.1. I used manual from here, but have problem with specifying port for connection from server(slave) to client(master). When I'm using client.rmi.localport
in jmeter.properties on master the following error appears:
ERROR o.a.j.u.JMeterUtils: Error in rconfigure() method java.rmi.MarshalException: error marshalling arguments; nested exception is: java.io.NotSerializableException: org.apache.jmeter.JMeter$ListenToTest
I was able to manage with other ports, only this one gives me trouble. I'm using nonGUI mode. How can I fix this/specify port?
Logs from master:
[...]

Edit: Changed JMeter to version 5.2 due to problem in comments.
Disabling the secure channel among client and servers helped me - I had this error no more and could specify ports. However I suggest doing it ONLY if your environment (both client and servers) work in private network.
