JMX Remote Connection - Connection Refused

[Pedro Felgueiras]

Hy all, 

I'm trying to connect to Jira by JMX. 

I have read this documentation : https://confluence.atlassian.com/adminjiraserver083/live-monitoring-using-the-jmx-interface-976768443.html

My setenv.sh have this config:

CATALINA_OPTS="-Dcom.sun.management.jmxremote ${CATALINA_OPTS}"
CATALINA_OPTS="-Dcom.sun.management.jmxremote.port=8099 ${CATALINA_OPTS}"
CATALINA_OPTS="-Dcom.sun.management.jmxremote.password.file=/var/atlassian/application-data/jira/jmxremote.password ${CATALINA_OPTS}"
export CATALINA_OPTS

There is a file on /var/atlassian/application-data/jira/jmxremote.password with 777 with: 

monitorRole 123
controlRole 456

When i try to remote connecti lunching the jconsole with debug (jconsole -debug) I got the following output: 

java.rmi.ConnectException: Connection refused to host: 127.0.1.1; nested exception is:

Here is a JVM Config to run it on localhost: https://pastebin.com/btm56qHh

Since it runs on localhost only, i dont have additional security here. If i want to connect to it from remote PC, i use a SSH Tunnel.
