Jconsole cannot connect

I am using VNC to connect to a server. I am able to VNC into the server, and open Jconsole, but cannot get it to connect to my process whether I include the PID or try connecting using the GUI. The weird thing is all the processes show up in the GUI. See below.
I get this when I try connecting:
Is there something I need to do in order to get Jconsole working locally on a Linux server over VNC?
Fix found here: You need to pass to the VM:
Edit - Fixed the
=fals error mentioned in comments.
If it reports 127.0. 0.1, JConsole would not be able to connect to the JVM running on that Linux machine. To fix this issue, edit /etc/hosts so that the hostname resolves to the host address. Check if the Linux machine is configured to accept packets from the host where JConsole runs on to connect to the application. JConsole cannot connect to Anagrams because it was not started with the correct Java VM or with the correct options. Connecting JConsole to a Remote Process When the connection dialog opens, you are also given the option of connecting to a remote process.
In my case, I also had to add this option to get Jconsole to connect to the process.

The issue is that when you start JConsole only Java processes started by the same user are listed in the connection dialog. Resolution: Connect to the Tomcat JConsole cannot connect to PID using remote desktop to Windows 2003 Server. I have JMX enabled java program running as a Windows Service under local system account using a service wrapper.
Add the following parameters to your java Application and run it
-Djava.rmi.server.hostname=DOMAIN_PUBLIC_URL -Dcom.sun.management.jmxremote.port=PORTNUMBER -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false
DOMAIN_PUBLIC_URL - Like your instance public address
PORTNUMBER - 9955
Launch jconsole in your ubuntu from terminal command and go to remote connection and paste the DOMAIN_PUBLIC_URL and PORT and Connect it without username and password like insecure connection.
Make sure to expose the port number on your AWS Server Instance.

Well, you cannot download JConsole separately. If you want to use JConsole you need to have Java SE Development Kit (JDK) installed on your system. Since Now use VisualVM or JConsole on your workstation to establish a connection to rmiRegistryPortPlatform, 9840 in our sample. If there are no more firewalls between workstation and server it should work.
But when you open your jconsole on your local computer to connect I also wonder why the rmi server can't automatically pick up a local ip… Start JConsole / Java VisualVM / Java Mission Control to connect to your Java Process using the following URL This works, cause JConsole / Java VisualVM / Java Mission Control thinks you connect to a Port on your local Windows machine. but Putty send all payload to the port 15666 to your linux machine.
- There's nothing you need to do that would be different from doing it sitting at the physical keyboard. Does the
ts_watchdogprogram disallow VM management?
- No I run the same program from the same Executable Jar as a service using nohup java -jar [path] & ; Then I run jconosle PID and I am connected. If it makes a difference my laptop is a mac and the server is ubuntu.
- At the end of the line it is not fals, but false. But it is ok! Thank you!
- this also required in MAC I guess.
