Elasticsearch input with AWS ES as service

Elastic Stack Logstash
1

wondering if anyone has tried streaming data out of AWS ES with the elasticsearch input plugin.. i can write to it fine, but seemingly can't read with the input plugin --

A plugin had an unrecoverable error. Will restart this plugin.
  Plugin: <LogStash::Inputs::Elasticsearch hosts=>["*****************************.es.amazonaws.com"], port=>80, index=>"nginx-2015.11.17", size=>1000, scroll=>"5m", docinfo=>true, scan=>true, debug=>false, codec=><LogStash::Codecs::JSON charset=>"UTF-8">, query=>"{\"query\": { \"match_all\": {} } }", docinfo_target=>"@metadata", docinfo_fields=>["_index", "_type", "_id"], ssl=>false>
  Error: Connection refused - Connection refused {:level=>:error}

The IP can definitely talk with the es domain..

telnet *****************************.es.amazonaws.com 80
Trying ************...
Connected to *****************************.es.amazonaws.com.
