Hi there, I have been trying to solve this problem for a day. I couldn't find any solutions. ```auto [2020-11-12T20:07:47,943][INFO][logstash.filters.geoip][main] Using geoip database {:path=>"/opt/logstash/vendor/geoip/GeoLite2-City.mmdb"} [2020-11-12T20:07:48,183][INFO][logstash.outputs.elasticsearch][main] Using a default mapping template {:es_version=>7, :ecs_compatibility=>:disabled} [2020-11-12T20:07:48,508][INFO][logstash.outputs.elasticsearch][main] Attempting to install template {:manage_template=>{"index_patterns"=>"cowrie-logstash-*", "version"=>60001, "settings"=>{"index.refresh_interval"=>"5s", "number_of_shards"=>1, "index.lifecycle.name"=>"logstash-policy", "index.lifecycle.rollover_alias"=>"cowrie-logstash"}, "mappings"=>{"dynamic_templates"=>[{"message_field"=>{"path_match"=>"message", "match_mapping_type"=>"string", "mapping"=>{"type"=>"text", "norms"=>false}}}, {"string_fields"=>{"match"=>"*", "match_mapping_type"=>"string", "mapping"=>{"type"=>"text", "norms"=>false, "fields"=>{"keyword"=>{"type"=>"keyword", "ignore_above"=>256}}}}}], "properties"=>{"@timestamp"=>{"type"=>"date"}, "@version"=>{"type"=>"keyword"}, "geoip"=>{"dynamic"=>true, "properties"=>{"ip"=>{"type"=>"ip"}, "location"=>{"type"=>"geo_point"}, "latitude"=>{"type"=>"half_float"}, "longitude"=>{"type"=>"half_float"}}}}}}} [2020-11-12T20:07:48,704][INFO][logstash.javapipeline][main] Starting pipeline {:pipeline_id=>"main", "pipeline.workers"=>2, "pipeline.batch.size"=>125, "pipeline.batch.delay"=>50, "pipeline.max_inflight"=>250, "pipeline.sources"=>["/etc/logstash/conf.d/beats-input.conf"], :thread=>"#"} [2020-11-12T19:53:03,676][FATAL][logstash.runner] An unexpected error occurred! {:error=>#, :backtrace=>["/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-elasticsearch-10.7.0-java/lib/logstash/outputs/elasticsearch/http_client/manticore_adapter.rb:80:in `perform_request'", "/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-elasticsearch-10.7.0-java/lib/logstash/outputs/elasticsearch/http_client/pool.rb:332:in `perform_request_to_url'", "/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-elasticsearch-10.7.0-java/lib/logstash/outputs/elasticsearch/http_client/pool.rb:319:in `block in perform_request'", "/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-elasticsearch-10.7.0-java/lib/logstash/outputs/elasticsearch/http_client/pool.rb:414:in `with_connection'", "/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-elasticsearch-10.7.0-java/lib/logstash/outputs/elasticsearch/http_client/pool.rb:318:in `perform_request'", "/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-elasticsearch-10.7.0-java/lib/logstash/outputs/elasticsearch/http_client/pool.rb:326:in `block in Pool'", "/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-elasticsearch-10.7.0-java/lib/logstash/outputs/elasticsearch/http_client.rb:341:in `exists?'", "/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-elasticsearch-10.7.0-java/lib/logstash/outputs/elasticsearch/http_client.rb:359:in `rollover_alias_exists?'", "/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-elasticsearch-10.7.0-java/lib/logstash/outputs/elasticsearch/ilm.rb:91:in `maybe_create_rollover_alias'", "/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-elasticsearch-10.7.0-java/lib/logstash/outputs/elasticsearch/ilm.rb:10:in `setup_ilm'", "/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-elasticsearch-10.7.0-java/lib/logstash/outputs/elasticsearch/common.rb:50:in `block in setup_after_successful_connection'"]} ``` I got this error. I am going to send cowrie honeypots logs . So here is my conf file. ```auto output { if [type] == "cowrie" { elasticsearch { hosts => ["127.0.0.1:9200"] user => "logstash_internal" password => "XXXXXXXX" ilm_enabled => auto ilm_rollover_alias => "cowrie-logstash" } #file { # path => "/tmp/cowrie-logstash.log" # codec => json #} stdout { codec => rubydebug } } ``` I gave privileges to logstash\_internal user. ---

So logstash is able to connect to elasticsearch but when it tries to setup ilm it sends a request to elasticsearch to determine whether the rollover index exists. That is getting an error. The elasticsearch logs may give a better error message to explain why it is rejecting the request. One possibility would be a 403 (possibly your user has the [wrong role](https://github.com/logstash-plugins/logstash-output-elasticsearch/issues/907)). Check the elasticsearch logs and enable log.level debug in logstash in case you have a problem with certificates or keys. ---

Thank you Badger. logstash\_internal user has logstash\_writer role which has all cluster privileges and as index privileges it has cowrie-logstash-\* indicies all privileges. I changed logging to debug but i am not sure where to look. There are too much information. There is a debug log just before fatal error. Can it be related? `[2020-11-12T21:38:40,692][DEBUG][logstash.outputs.elasticsearch][main] Found existing Elasticsearch template. Skipping template management {:name=>"cowrie-logstash"}` ---
