`http://elasticsearch:9200/` is the [default URL](https://www.elastic.co/guide/en/logstash/7.8/monitoring-internal-collection-legacy.html#logstash-monitoring-default-legacy) for logstash internal monitoring.  
The warning probably means that connection is not possible because there is no host called `elasticsearch` listening on port 9200, you can test the connection with `curl http://elasticsearch:9200/` and will probably get a similar failure (or just `ping elasticsearch`)

If you do not use monitoring and have no hostname called `elasticsearch`, you can disable monitoring or change the destination hosts.
