I am trying to connect to a remote jboss instance running on the server. I am using the following connection url
Services: JMX: Remoting-JMX: //90.214.64.170: 9999
When I do this, I get the following 2 errors in the console window

After choosing insecure I am presented with this

I have, before connecting via jconsole, I also went to the bin directory of my jboss server and ran it ./jconsole.sh, which displays the following at the command prompt
CLASSPATH /usr/bin/java/jdk1.8.0_11/lib/jconsole.jar:/usr/bin/java/jdk1.8.0_11/lib/tools.jar:/var/opt/jboss/modules/system/layers/base/org/jboss/remoting-jmx/main/remoting-jmx-1.1.2.Final-redhat-1.jar:/var/opt/jboss/modules/system/layers/base/org/jboss/remoting3/main/jboss-remoting-3.2.18.GA-redhat-1.jar:/var/opt/jboss/modules/system/layers/base/org/jboss/logging/main/jboss-logging-3.1.2.GA-redhat-1.jar:/var/opt/jboss/modules/system/layers/base/org/jboss/xnio/main/xnio-api-3.0.7.GA-redhat-1.jar:/var/opt/jboss/modules/system/layers/base/org/jboss/xnio/nio/main/xnio-nio-3.0.7.GA-redhat-1.jar:/var/opt/jboss/modules/system/layers/base/org/jboss/sasl/main/jboss-sasl-1.0.3.Final-redhat-1.jar:/var/opt/jboss/modules/system/layers/base/org/jboss/marshalling/main/jboss-marshalling-1.4.2.Final-redhat-1.jar:/var/opt/jboss/modules/system/layers/base/org/jboss/marshalling/river/main/jboss-marshalling-river-1.4.2.Final-redhat-1.jar:/var/opt/jboss/modules/system/layers/base/org/jboss/as/cli/main/jboss-as-cli-7.3.0.Final-redhat-14.jar:/var/opt/jboss/modules/system/layers/base/org/jboss/staxmapper/main/staxmapper-1.1.0.Final-redhat-2.jar:/var/opt/jboss/modules/system/layers/base/org/jboss/as/protocol/main/jboss-as-protocol-7.3.0.Final-redhat-14.jar:/var/opt/jboss/modules/system/layers/base/org/jboss/dmr/main/jboss-dmr-1.2.0.Final-redhat-1.jar:/var/opt/jboss/modules/system/layers/base/org/jboss/as/controller-client/main/jboss-as-controller-client-7.3.0.Final-redhat-14.jar:/var/opt/jboss/modules/system/layers/base/org/jboss/threads/main/jboss-threads-2.1.1.Final-redhat-1.jar
I'm not sure what else I can try (also by opening port 9999) to get this to work, does anyone have any tips or tricks that can help with this?
thank
EDIT
After changing my standalone.conf file to
if [ "x$JAVA_OPTS" = "x" ]; then
JAVA_OPTS="-Xms1303m -Xmx1303m -XX:MaxPermSize=256m -Djava.net.preferIPv4Stack=true"
JAVA_OPTS="$JAVA_OPTS -Djboss.modules.system.pkgs=$JBOSS_MODULES_SYSTEM_PKGS -Djava.awt.headless=true"
JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote"
JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.port=9999"
JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.ssl=false"
JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.authenticate=false"
else
echo "JAVA_OPTS already set in environment; overriding default settings with values: $JAVA_OPTS"
fi
I still cannot connect - with the same errors as above
