Hi All,  
I am trying to install plugin  
logstash-output-email ,  
logstash-filter-elapsed ,  
logstash-filter-aggregate and  
logstash-filter-date , in my secured AWS cluster.

But I am getting 'ERROR: Something went wrong when installing logstash-filter-date, message: 403 "Forbidden"

Could any one please help me on this?  
Is it I am in secure(firewall restricted) and what are urls that I need to consider for whiteline

Whitelisting [rubygems.org](http://rubygems.org) should be enough, but I'd record the network traffic with tcpdump or Wireshark to see exactly what's going on.
