I am using version 8.1.2. It is not running successfully elastic search don't authorize Logstash.

The error from Logstash is [main] Attempted to resurrect connection to dead ES instance, but got an error {:url=>"http://elasticsearch:9200/", :exception=>LogStash::Outputs::ElasticSearch::HttpClient::Pool::BadResponseCodeError, :message=>"Got response code '401' contacting Elasticsearch at URL 'http://elasticsearch:9200/'"}
