Hi All, I'm trying to connect to Kibana after running the logstash but could see that the connection is getting refused after running the file. Following are the responses on batch. Could you please let me know when and why does this error occur. // log [06:30:52.310] [error][data][elasticsearch] [ConnectionError]: connect ECONNREFUSED 172.31.201.229:9200 log [06:30:53.535] [warning][elasticsearch][monitoring] Unable to revive connection: [http://a0310pnpbiapp02:9200/](http://a0310pnpbiapp02:9200/) log [06:30:53.536] [warning][elasticsearch][monitoring] No living connections log [06:30:53.540] [warning][licensing][plugins] License information could not be obtained from Elasticsearch due to Error: No Living connections error log [06:30:57.322] [error][data][elasticsearch] [ConnectionError]: connect ECONNREFUSED 172.31.201.229:9200 log [06:31:02.336] [error][data][elasticsearch] [ConnectionError]: connect ECONNREFUSED 172.31.201.229:9200 log [06:31:07.333] [error][data][elasticsearch] [ConnectionError]: connect ECONNREFUSED 172.31.201.229:9200 log [06:31:12.352] [error][data][elasticsearch] [ConnectionError]: connect ECONNREFUSED 172.31.201.229:9200 log [06:31:17.387] [error][data][elasticsearch] [ConnectionError]: connect ECONNREFUSED 172.31.201.229:9200 log [06:31:22.417] [error][data][elasticsearch] [ConnectionError]: connect ECONNREFUSED 172.31.201.229:9200 log [06:31:23.547] [warning][elasticsearch][monitoring] Unable to revive connection: [http://a0310pnpbiapp02:9200/](http://a0310pnpbiapp02:9200/) log [06:31:23.548] [warning][elasticsearch][monitoring] No living connections log [06:31:23.552] [warning][licensing][plugins] License information could not be obtained from Elasticsearch due to Error: No Living connections error log [06:31:27.412] [error][data][elasticsearch] [ConnectionError]: connect ECONNREFUSED 172.31.201.229:9200 log [06:31:32.430] [error][data][elasticsearch] [ConnectionError]: connect ECONNREFUSED 172.31.201.229:9200 log [06:31:37.450] [error][data][elasticsearch] [ConnectionError]: connect ECONNREFUSED 172.31.201.229:9200 log [06:31:42.476] [error][data][elasticsearch] [ConnectionError]: connect ECONNREFUSED 172.31.201.229:9200 log [06:31:47.479] [error][data][elasticsearch] [ConnectionError]: connect ECONNREFUSED 172.31.201.229:9200 log [06:31:52.484] [error][data][elasticsearch] [ConnectionError]: connect ECONNREFUSED 172.31.201.229:9200 log [06:31:53.568] [warning][elasticsearch][monitoring] Unable to revive connection: [http://a0310pnpbiapp02:9200/](http://a0310pnpbiapp02:9200/) log [06:31:53.569] [warning][elasticsearch][monitoring] No living connections log [06:31:53.570] [warning][licensing][plugins] License information could not be obtained from Elasticsearch due to Error: No Living connections error log [06:31:57.492] [error][data][elasticsearch] [ConnectionError]: connect ECONNREFUSED 172.31.201.229:9200 ---

HI @vaishalik03, Welcome to the Elastic community. Could you first try to connect with `curl` command from the same machine ? Let's make sure there is no firewall blocker or any. ---
