It looks like the Elasticsearch service you are trying to connect to with Logstash is not available. Is your cluster up and available at the address specified in your Logstash config?

Yes. Elastic services is up and running fine.

Have you evaluate LS pipeline utilization or have you checked elasticsearch logs? Should be some timeout, high CPU or similar.
