I am using the docker configuration on the server. I am not that much familiar with docker. Before docker, it is working fine but now it is not working and throwing an error.

```auto
elasticsearch - Attempted to resurrect connection to dead ES instance, but got an error.
 {:url=>"http://elastic:xxxxxx@xxx.xxx.xxx.xx:9200/", 
:error_type=>LogStash::Outputs::ElasticSearch::HttpClient::Pool::HostUnreachableError, 
:error=>"Elasticsearch Unreachable: [http://elastic:xxxxxx@xxx.xxx.xxx.xx:9200/]
[Manticore::ConnectTimeout] connect timed out"}

```

My output configuration file is:

```auto
output{
elasticsearch {
    hosts=>"http://xxx.xxx.xxx.xx:9200"
    index => "final_inter_sms"
    user=> "xxx"
    password=> "xxxxx"
    document_id=>"%{[ReferenceId]}"
  }
stdout{
    codec => rubydebug
  }
}

```
