Reading Rabbit MQ From LogStash (ELK Instance) - elasticsearch

Question

I have 2 servers, one RabbitMQ, and one ELK server.
Both are independently running as they should. My ELK instance receives input messages from several sources across my network, but both servers are in the same internal network.
I am trying to make LogStash read from RabbitMQ, to get any log messages i pushed into there.
Here's my logstash conf.d file:
input{
rabbitmq {
host => "1.66.66.66"
queue => "logs"
durable => true
exchange => "event.log"
threads => 1
prefetch_count => 50
port => 5672
user => "elk"
password => "*******"
}
}
filter{
}
output {
elasticsearch {
hosts => ["1.66.66.1:9200"]
sniffing => false
manage_template => false
index => "%{[#metadata][beat]}-%{+YYYY.MM.dd}"
document_type => "%{[#metadata][type]}"
}
}
After i run a config test ($ sudo service logstash configtest)
if get: ConfigTest OK
So this seems good.
But then when it runs i get the following error in my "/var/log/logstash/logstash.log" file:
{:timestamp=>"2017-06-15T10:28:18.727000-0400", :message=>"Connection refused (Connection refused)", :class=>"Manticore::SocketException", :backtrace=>["/opt/logstash/vendor/bundle/jruby/1.9/gems/manticore-0.6.0-java/lib/manticore/response.rb:37:in `initialize'", "org/jruby/RubyProc.java:281:in `call'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/manticore-0.6.0-java/lib/manticore/response.rb:79:in `call'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/manticore-0.6.0-java/lib/manticore/response.rb:256:in `call_once'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/manticore-0.6.0-java/lib/manticore/response.rb:153:in `code'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/elasticsearch-transport-1.0.18/lib/elasticsearch/transport/transport/http/manticore.rb:84:in `perform_request'", "org/jruby/RubyProc.java:281:in `call'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/elasticsearch-transport-1.0.18/lib/elasticsearch/transport/transport/base.rb:257:in `perform_request'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/elasticsearch-transport-1.0.18/lib/elasticsearch/transport/transport/http/manticore.rb:67:in `perform_request'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/elasticsearch-transport-1.0.18/lib/elasticsearch/transport/transport/sniffer.rb:32:in `hosts'", "org/jruby/ext/timeout/Timeout.java:147:in `timeout'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/elasticsearch-transport-1.0.18/lib/elasticsearch/transport/transport/sniffer.rb:31:in `hosts'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/elasticsearch-transport-1.0.18/lib/elasticsearch/transport/transport/base.rb:79:in `reload_connections!'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-elasticsearch-2.7.1-java/lib/logstash/outputs/elasticsearch/http_client.rb:72:in `sniff!'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-elasticsearch-2.7.1-java/lib/logstash/outputs/elasticsearch/http_client.rb:60:in `start_sniffing!'", "org/jruby/ext/thread/Mutex.java:149:in `synchronize'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-elasticsearch-2.7.1-java/lib/logstash/outputs/elasticsearch/http_client.rb:60:in `start_sniffing!'", "org/jruby/RubyKernel.java:1479:in `loop'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-elasticsearch-2.7.1-java/lib/logstash/outputs/elasticsearch/http_client.rb:59:in `start_sniffing!'"], :level=>:error}
If, from my ELK server do:
curl -X GET http://1.66.66.1:9200
I get the proper response:
{
"name" : "Hera",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "-NmCwDk_RA2qzTwWlNNizQ",
"version" : {
"number" : "2.4.5",
"build_hash" : "c849dd13904f53e63e88efc33b2ceeda0b6a1276",
"build_timestamp" : "2017-04-24T16:18:17Z",
"build_snapshot" : false,
"lucene_version" : "5.5.4"
},
"tagline" : "You Know, for Search"
}
If you know anything i can try, that would be much appreciated, I am running Ubuntu 16.04 on both servers. Thanks!
