We have a 3 node elasticsearch cluster set up. The logstash ouput config looks like this:

```auto
output {
    elasticsearch {
        hosts => ["node1:9200",
                  "node2:9200",
                  "node3:9200"
                  ]
        manage_template => false
        index => "%{[@metadata][beat]}-%{+YYYY.MM.dd}"
        document_type => "log"
    }

}

```

I had to take down node1 of elasticsearch cluster for some maintenance. However logstash didn't auto connect to the other nodes in the elastic search cluster even though they were up.

I could see the below error in the logstash logs:

[2021-02-03T16:35:50,391][INFO][logstash.outputs.elasticsearch] Running health check to see if an Elasticsearch connection is working {:healthcheck\_url=\>[http://node1:9200/](http://node1:9200/), :path=\>"/"} [2021-02-03T16:35:50,394][WARN][logstash.outputs.elasticsearch] Attempted to resurrect connection to dead ES instance, but got an error. {:url=\>"[http://node1:9200/](http://node1:9200/)", :error\_type=\>LogStash::Outputs::ElasticSearch::HttpClient::Pool::HostUnreachableError, :error=\>"Elasticsearch Unreachable: [[http://node1:9200/](http://node1:9200/)][Manticore::SocketException] Connection refused"}

We are using logstash version- 1:6.2.2-1 and elasticsearch- 6.2.2

Are they any settings that can make logstash auto connect to other elastic search nodes that are healthy? Please advise.TIA
