Hey recently deployed Elasticsearch via ECK and Logstash with deployment the problem I'm getting is when the connection between them two when I check the logs I get the following error: [2019-12-20T17:47:53,592][WARN][logstash.outputs.elasticsearch] Attempted to resurrect connection to dead ES instance, but got an error. {:url=\>"[https://elastic:xxxxxx@10.15.248.234:9200/](https://elastic:xxxxxx@10.15.248.234:9200/)", :error\_type=\>LogStash::Outputs::ElasticSearch::HttpClient::Pool::HostUnreachableError, :error=\>"Elasticsearch Unreachable: [[https://elastic:xxxxxx@10.15.248.234:9200/](https://elastic:xxxxxx@10.15.248.234:9200/)][Manticore::ClientProtocolException] PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target"} "Unable to find valid certification path to requested target" I've turned off this feature inside Elasticsearch ``` tls: selfSignedCertificate: disabled: true ``` Not too sure why I'm still getting these error's ---
