@hcwwadmin - I apologize for the inconvenience. I failed to properly update the 50-outputs.conf file. The host should have been http://elastic:9200 and not http://localhost:9200

Additionally, I found that both the 35-ruels-desc.conf and 36-ports-desc.conf files resulted in logstash crashing.

Please give it another try with the revised files. I've tested without issue.

[hcwwadmin]

the error is gone
thanks for your help

@kk0201 - thanks! The issue was just fixed...had a typo where http://localhost:9200 should have been http://es01:9200
