Error Bundler::HTTPError, retrying 1/10

Hi All

Tried to install
bin/logstash-plugin install --local --no-verify /tmp/logstash-core-2.3.4-java.gem

but I keep getting the HTTPError. I tried setting the HTTP_PROXY=
still same issue. I will definitely not be able to access from my node due to security reasons. Any workaround for this will be greatly appreciated.

All these effort is to install logstash-output-zabbix which fails.
