Logstash Rabbitmq connection refused

Have installed Elasticsearch-6.6.0 and kibana-6.6.0 in Windows core 2016 Server it is up and running, I had to index the data from Rabbitmq, so downloaded and unzipped logstash-6.0.0 and made a config file for rabbitmq as follows

input {
    rabbitmq {
        arguments => { "x-ha-policy" => "all" }
        host => "172.xx.xx.xx"
        queue => "xx.flow.queue"
        #durable => true
        key => "flowtrack"
        exchange => "xx.test.exchange"
        threads => 120
        exclusive => false
        prefetch_count => 512
        vhost => "/"
        port => 5672
        user => "usr"
        password => "Pass@123"
    }
}
output {
  elasticsearch {
    hosts => ["172.xx.xx.xx:9200"]
  }
}

Ran logstash through commandline as follows

    c:\logstash-6.0.0>bin\logstash -f config\rabbitmq.conf

but it throws error as follows

 [2019-02-20T23:01:28,696][ERROR][logstash.inputs.rabbitmq ] RabbitMQ connection error, will retry. {:error_message=>"Connection to localhost:5672 refused", :exception=>"MarchHare::ConnectionRefused"}
    [2019-02-20T23:01:28,696][ERROR][logstash.inputs.rabbitmq ] RabbitMQ connection error, will retry. {:error_message=>"Connection to localhost:5672 refused", :exception=>"MarchHare::ConnectionRefused"}

Port 5672 is open in host Let me know if i have missed anything in configuration which is leading to this error.

Thanks in advance

Have found the issue, it was due to route not enabled in server. Now connection between Logstash and Rabbitmq is established and indexing is done.
