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:
-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false

Edit - Fixed the =fals error mentioned in comments.
In my case, I also had to add this option to get Jconsole to connect to the process.
-Djava.rmi.server.hostname=localhost
Adding below property as VM argument in Run Configurations --> Arguments --
-Dcom.sun.management.jmxremote=true
Remote JConsole
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.
