connection refused error when trying to install plugins - ruby

Question

i'm trying to install the logstash-input-jmx plugin but I keep getting a
ERROR: Something went wrong when installing , message: Connection refused - Connection refused
I've tried to set the proxy before running but no luck:
export http_proxy=http://proxy.com:8099
export https_proxy=http://proxy.com:8099
./logstash-plugin install logstash-input-jmx
I've edited the logstash-plugin file to include the proxy like this:
#!/bin/sh
unset CDPATH
. "$(cd `dirname $0`/..; pwd)/bin/logstash.lib.sh"
setup
# bin/logstash-plugin is a short lived ruby script thus we can use aggressive "faster starting JRuby options"
# see https://github.com/jruby/jruby/wiki/Improving-startup-time
export JRUBY_OPTS="$JRUBY_OPTS -J-XX:+TieredCompilation -J-XX:TieredStopAtLevel=1 -J-noverify -X-C -Xcompile.invokedynamic=false"
export http_proxy=http://proxy.com:8099
export https_proxy=http://proxy.com:8099
ruby_exec "${LOGSTASH_HOME}/lib/pluginmanager/main.rb" "$#"
but got the same error
I've tried to even follow this github page: https://github.com/logstash-plugins/logstash-input-jmx
but when I get to bin/logstash-plugin install --no-verify...I still got the same error...

I was able to fix this by adding in the proxy to LS_JAVA_OPTS
LS_JAVA_OPTS='-Dhttp.useProxy=true -Dhttp.proxyHost=http://proxy.com -Dhttp.proxyPort=8099 -Dhttps.proxyHost=http://proxy.com -Dhttps.proxyPort=8099' ./logstash-plugin install logstash-input-jmx
