After setting the following environment variables: http\_proxy and https\_proxy to [http://localhost:3128](http://localhost:3128) , I attempted to download the exec output plugin by typing:

./bin/logstash-plugin install logstash-output-exec

I received the following error message:  
Unable to download data from [https://rubygems.org](https://rubygems.org) - Errno::ECONNREFUSED: Connection refused - Failed to open TCP connection to localhost:3128 \<Connection refused - connect\<2\> for "localhost" port 3128\> [https://rubygems.org/latest\_specs.4.8.gz](https://rubygems.org/latest_specs.4.8.gz)

I am running this from a workstation behind the corporate firewall.  
Is this a ruby issue? logstash issue? or network/workstation issue?
