Question

Hi Guys,

I am trying to run the Logstash server, but it is showing me the below error.

[2020-06-19T07:30:14,013][WARN ][logstash.outputs.elasticsearch] Attempted to resurrect connection to dead ES instance, but got an error. {:url=>"http://localhost:9200/", :error_type=>LogStash::Outputs::ElasticSearch::HttpClient::Pool::HostUnreachableError, :error=>"Elasticsearch Unreachable: [http://localhost:9200/][Manticore::SocketException] Connection refused (Connection refused)"}

Hi@akhtar,

Logstash is trying to connect the ElasticSearch server. But seems it is unable to connect your ElasticSearch. Check IP and port no. in your Logstash configuration file. It should be IP:9200 format. Also, make sure your ElasticSearch is up before starting Logstash service.

Check your ElasticSearch service and network connectivity.
