Hi @Mario_Castro Thanks for your response. I am following quick start guide and didn't change something significant. I think the original problem is solved by changing the host from http to https but another problem comes up and it is connection refused problem. > 2020-01-23T14:00:36.042Z ERROR pipeline/output.go:100 Failed to connect to backoff(elasticsearch([https://quickstart-es-http:9200](https://quickstart-es-http:9200))): Get [https://quickstart-es-http:9200](https://quickstart-es-http:9200): dial tcp 23.217.138.110:9200: connect: connection refused > 2020-01-23T14:00:36.042Z INFO pipeline/output.go:93 Attempting to reconnect to backoff(elasticsearch([https://quickstart-es-http:9200](https://quickstart-es-http:9200))) with 3 reconnect attempt(s) > 2020-01-23T14:00:36.042Z INFO [publisher] pipeline/retry.go:196 retryer: send unwait-signal to consumer > 2020-01-23T14:00:36.042Z INFO [publisher] pipeline/retry.go:198 done > 2020-01-23T14:00:36.042Z INFO [publisher] pipeline/retry.go:173 retryer: send wait signal to consumer > 2020-01-23T14:00:36.042Z INFO [publisher] pipeline/retry.go:175 done The solutions out there are referring to modifying network.host field in elasticsearch yaml file. what do you suggest? --- _[View the full topic](https://discuss.elastic.co/t/dns-lookup-failure-elasticsearch/216140)._
