I am trying to do distributed testing using JMeter over Azure VMs behind the firewall using the conventional ways defined in most of the articles. I have tried all the possible options defined in the following site and some other websites. I tried to define a specific port for the slave machine as the VM is over the firewall and only some specific ports are open. But nothing worked. Every time I got this following error.
Connection refused to host: IP address: nested exception is: java.net.ConnectException:Connection timed out:connect
