HI, I am getting below error while establishing connection from logstash pipeline to Elasticsearch. I am able to do the telnet from logstash server to Elasticsearch server but not able to establish the connection. logstash.conf file - input { stdin{} } output { Elasticsearch { hosts =\> ["10.128.0.3:9200"] index =\> "%{[@metadata][beat]}-%{+YYYY.MM.dd}" } } Error message - Elasticsearch - New Elasticsearch output {:class=\>"LogStash::Outputs::Elasticsearch", :hosts=\>["[//10.128.0.3:9200](https://10.128.0.3:9200)"]} [INFO] 2022-06-15 11:39:43.115 [[main]-pipeline-manager] Elasticsearch - Elasticsearch pool URLs updated {:changes=\>{:removed=\>, :added=\>[[http://10.128.0.3:9200/](http://10.128.0.3:9200/)]}} [ERROR] 2022-06-15 11:39:43.687 [[main]-pipeline-manager] javapipeline - Pipeline error {:pipeline\_id=\>"main", :exception=\>#\, :backtrace=\>["/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-Elasticsearch-11.4.1-java/lib/logstash/outputs/Elasticsearch/http\_client/pool.rb:245:in `block in healthcheck!'", "org/jruby/RubyHash.java:1415:in `each'", "/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-Elasticsearch-11.4.1-java/lib/logstash/outputs/Elasticsearch/http\_client/pool.rb:238:in `healthcheck!'", "/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-elasticsearch-11.4.1-java/lib/logstash/outputs/elasticsearch/http_client/pool.rb:370:in `update\_urls'", "/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-Elasticsearch-11.4.1-java/lib/logstash/outputs/Elasticsearch/http\_client/pool.rb:87:in `update_initial_urls'", "/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-elasticsearch-11.4.1-java/lib/logstash/outputs/elasticsearch/http_client/pool.rb:81:in `start'", "/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-Elasticsearch-11.4.1-java/lib/logstash/outputs/Elasticsearch/http\_client.rb:358:in `build_pool'", "/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-elasticsearch-11.4.1-java/lib/logstash/outputs/elasticsearch/http_client.rb:63:in `initialize'", "/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-Elasticsearch-11.4.1-java/lib/logstash/outputs/Elasticsearch/http\_client\_builder.rb:106:in `create_http_client'", "/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-elasticsearch-11.4.1-java/lib/logstash/outputs/elasticsearch/http_client_builder.rb:102:in `build'", "/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-Elasticsearch-11.4.1-java/lib/logstash/plugin\_mixins/Elasticsearch/common.rb:34:in `build_client'", "/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-elasticsearch-11.4.1-java/lib/logstash/outputs/elasticsearch.rb:279:in `register'", "org/logstash/config/ir/compiler/OutputStrategyExt.java:131:in `register'", "org/logstash/config/ir/compiler/AbstractOutputDelegatorExt.java:68:in `register'", "/usr/share/logstash/logstash-core/lib/logstash/java\_pipeline.rb:233:in `block in register_plugins'", "org/jruby/RubyArray.java:1821:in `each'", "/usr/share/logstash/logstash-core/lib/logstash/java\_pipeline.rb:232:in `register_plugins'", "/usr/share/logstash/logstash-core/lib/logstash/java_pipeline.rb:598:in `maybe\_setup\_out\_plugins'", "/usr/share/logstash/logstash-core/lib/logstash/java\_pipeline.rb:245:in `start_workers'", "/usr/share/logstash/logstash-core/lib/logstash/java_pipeline.rb:190:in `run'", "/usr/share/logstash/logstash-core/lib/logstash/java\_pipeline.rb:142:in `block in start'"], "pipeline.sources"=\>["/etc/logstash/conf.d/beats.conf"], :thread=\>"#\"} [INFO] 2022-06-15 11:39:43.691 [[main]-pipeline-manager] javapipeline - Pipeline terminated {"pipeline.id"=\>"main"} [ERROR] 2022-06-15 11:39:43.719 [Converge PipelineAction::Create] agent - Failed to execute action {:id=\>:main, :action\_type=\>LogStash::ConvergeResult::FailedAction, :message=\>"Could not execute action: PipelineAction::Create, action\_result: false", :backtrace=\>nil} [INFO] 2022-06-15 11:39:43.843 [LogStash::Runner] runner - Logstash shut down. ---

> [@harijld](#): > > [[http://10.128.0.3:9200/](http://10.128.0.3:9200/)]... Could not connect to a compatible version of Elasticsearch If you do a get to that URL, you will get JSON back which includes things like the the minimum version that is wire protocol compatible. Generally you need logstash and elasticsearch to be the same version, or very close thereto. See [this](https://discuss.elastic.co/t/logtstash-updating-fron-7-9-to-7-16-2/298453/2) thread. ---
