Could not communicate to Elasticsearch, resetting connection and trying again. EOFError (EOFError)[Fluentd using helm on kubernetes]

I'm installing elasticsearch, kibana and fluentd in kubernetes with helm chart Elasticsearch and kibana pods stand up smoothly, but fluentd pods don't stand up I get the following errors:
