Hello, our fscrawler is unable to make a connection with Elasticsearch in the linux server. Previously with the same configuration, it was working fine but don't know why suddenly we starts to face this issue -- we are using fscrawler 2.4 and after facing issue upgraded to 2.7 also. and our elk stack is 6.8.14 sharing logs for the same: ```auto kubectl logs fscrawler-cognitiveclaims-batch0-1641014100-9zqvg -n app-claimselk cronjob-claimselk-fscrawler-batch0 05:15:05,974 DEBUG [f.p.e.c.f.u.FsCrawlerUtil] Mapping [2/_settings.json] already exists 05:15:05,976 DEBUG [f.p.e.c.f.u.FsCrawlerUtil] Mapping [2/_settings_folder.json] already exists 05:15:05,982 DEBUG [f.p.e.c.f.u.FsCrawlerUtil] Mapping [5/_settings.json] already exists 05:15:05,983 DEBUG [f.p.e.c.f.u.FsCrawlerUtil] Mapping [5/_settings_folder.json] already exists 05:15:06,000 DEBUG [f.p.e.c.f.u.FsCrawlerUtil] Mapping [6/_settings.json] already exists 05:15:06,000 DEBUG [f.p.e.c.f.u.FsCrawlerUtil] Mapping [6/_settings_folder.json] already exists 05:15:06,004 DEBUG [f.p.e.c.f.FsCrawler] Starting job [processformstemplates]... 05:15:06,142 TRACE [f.p.e.c.f.FsCrawler] settings used for this crawler: [{ "name" : "processformstemplates0", "fs" : { "url" : "/usr/share/fscrawler/data", "update_rate" : "15m", "excludes" : ["*/~*"], "json_support" : false, "filename_as_id" : true, "add_filesize" : true, "remove_deleted" : false, "add_as_inner_object" : false, "store_source" : false, "index_content" : true, "attributes_support" : false, "raw_metadata" : false, "xml_support" : false, "index_folders" : true, "lang_detect" : false, "continue_on_error" : false, "pdf_ocr" : true, "ocr" : { "language" : "eng" } }, "elasticsearch" : { "nodes" : [ { "host" : "elasticsearch-claimselk-http.app-claimselk.svc.cluster.local", "port" : 9200, "scheme" : "HTTP" } ], "index" : "formslettersandtemplates", "bulk_size" : 100, "flush_interval" : "5s", "username" : "elastic" }, "rest" : { "port" : 0 } }] **05:15:06,819 WARN [f.p.e.c.f.c.ElasticsearchClientManager] failed to create elasticsearch client, disabling crawler...** **05:15:06,819 FATAL [f.p.e.c.f.FsCrawler] Fatal error received while running the crawler: [Connection refused]** **05:15:06,819 DEBUG [f.p.e.c.f.FsCrawler] error caught** **java.net.ConnectException: Connection refused** at sun.nio.ch.SocketChannelImpl.checkConnect(Native Method) ~[?:1.8.0_121] at sun.nio.ch.SocketChannelImpl.finishConnect(SocketChannelImpl.java:717) ~[?:1.8.0_121] at org.elasticsearch.client.http.impl.nio.reactor.DefaultConnectingIOReactor.processEvent(DefaultConnectingIOReactor.java:171) ~[elasticsearch-rest-client-6.0.0-beta1.jar:6.0.0-beta1] at org.elasticsearch.client.http.impl.nio.reactor.DefaultConnectingIOReactor.processEvents(DefaultConnectingIOReactor.java:145) ~[elasticsearch-rest-client-6.0.0-beta1.jar:6.0.0-beta1] at org.elasticsearch.client.http.impl.nio.reactor.AbstractMultiworkerIOReactor.execute(AbstractMultiworkerIOReactor.java:348) ~[elasticsearch-rest-client-6.0.0-beta1.jar:6.0.0-beta1] at org.elasticsearch.client.http.impl.nio.conn.PoolingNHttpClientConnectionManager.execute(PoolingNHttpClientConnectionManager.java:192) ~[elasticsearch-rest-client-6.0.0-beta1.jar:6.0.0-beta1] at org.elasticsearch.client.http.impl.nio.client.CloseableHttpAsyncClientBase$1.run(CloseableHttpAsyncClientBase.java:64) ~[elasticsearch-rest-client-6.0.0-beta1.jar:6.0.0-beta1] at java.lang.Thread.run(Thread.java:745) ~[?:1.8.0_121] 05:15:06,824 DEBUG [f.p.e.c.f.FsCrawlerImpl] Closing FS crawler [processformstemplates0] 05:15:06,824 DEBUG [f.p.e.c.f.FsCrawlerImpl] FS crawler Rest service stopped 05:15:06,824 DEBUG [f.p.e.c.f.c.ElasticsearchClientManager] Closing Elasticsearch client manager 05:15:06,824 DEBUG [f.p.e.c.f.c.ElasticsearchClient] Closing REST client 05:15:06,825 DEBUG [f.p.e.c.f.c.ElasticsearchClient] REST client closed 05:15:06,825 DEBUG [f.p.e.c.f.FsCrawlerImpl] ES Client Manager stopped 05:15:06,826 INFO [f.p.e.c.f.FsCrawlerImpl] FS crawler [processformstemplates0] stopped 05:15:06,827 DEBUG [f.p.e.c.f.FsCrawlerImpl] Closing FS crawler [processformstemplates0] 05:15:06,828 DEBUG [f.p.e.c.f.FsCrawlerImpl] FS crawler Rest service stopped 05:15:06,828 DEBUG [f.p.e.c.f.c.ElasticsearchClientManager] Closing Elasticsearch client manager 05:15:06,828 DEBUG [f.p.e.c.f.c.ElasticsearchClient] Closing REST client 05:15:06,828 DEBUG [f.p.e.c.f.c.ElasticsearchClient] REST client closed 05:15:06,828 DEBUG [f.p.e.c.f.FsCrawlerImpl] ES Client Manager stopped 05:15:06,828 INFO [f.p.e.c.f.FsCrawlerImpl] FS crawler [processformstemplates0] stopped ``` ---
