What to do when this appears in the logstash log?

[2020-12-04T09:46:50,568][WARN][logstash.outputs.elasticsearch][main] Marking url as dead. Last error: [LogStash::Outputs::ElasticSearch::HttpClient::Pool::HostUnreachableError] Elasticsearch Unreachable: [[http://localhost:9201/](http://localhost:9201/)][Manticore::SocketTimeout] Read timed out {:url=\>[http://localhost:9201/](http://localhost:9201/), :error\_message=\>"Elasticsearch Unreachable: [[http://localhost:9201/](http://localhost:9201/)][Manticore::SocketTimeout] Read timed out", :error\_class=\>"LogStash::Outputs::ElasticSearch::HttpClient::Pool::HostUnreachableError"}  
[2020-12-04T09:46:50,568][ERROR][logstash.outputs.elasticsearch][main] Attempted to send a bulk request to elasticsearch' but Elasticsearch appears to be unreachable or down! {:error\_message=\>"Elasticsearch Unreachable: [[http://localhost:9201/](http://localhost:9201/)][Manticore::SocketTimeout] Read timed out", :class=\>"LogStash::Outputs::ElasticSearch::HttpClient::Pool::HostUnreachableError", :will\_retry\_in\_seconds=\>2}

O que fazer quando aparece isso no log do logstash?

[2020-12-04T09: 46: 50,568] [WARN] [logstash.outputs.elasticsearch] [main] Marcando url como morto. Último erro: [LogStash :: Outputs :: ElasticSearch :: HttpClient :: Pool :: HostUnreachableError] Elasticsearch inacessível: [http: // localhost: 9201 /] [Manticore :: SocketTimeout] Tempo de leitura esgotado {: url =\> http: // localhost: 9201 /,: error\_message =\> "Elasticsearch inacessível: [http: // localhost: 9201 /] [Manticore :: SocketTimeout] Tempo limite de leitura esgotado",: error\_class =\> "LogStash :: Outputs :: ElasticSearch :: HttpClient :: Pool :: HostUnreachableError "}
