OK I installed x-pack and finally got all the credentials in the correct places(including winlogbeats on WEC) but now getting new error in logstash logs -
[2017-11-07T14:29:34,577][ERROR][logstash.outputs.elasticsearch] Encountered a retryable error. Will Retry with exponential backoff {:code=>403, :url=>"http://10.68.168.21:9200/_bulk"}

Hoping this is the last one!!!
