Hi , when using RestHighLevelClient , often the requests to Elasticsearch (index search, index requests etc) fail due to connection problems. ``` java.io.IOException: Connection reset by peer at sun.nio.ch.FileDispatcherImpl.read0(FileDispatcherImpl.java) ~[na:1.8.0_252] at sun.nio.ch.SocketDispatcher.read(SocketDispatcher.java:39) at sun.nio.ch.IOUtil.readIntoNativeBuffer(IOUtil.java:223) at sun.nio.ch.IOUtil.read(IOUtil.java:197) at sun.nio.ch.SocketChannelImpl.read(SocketChannelImpl.java:377) at org.apache.http.impl.nio.reactor.SessionInputBufferImpl.fill(SessionInputBufferImpl.java:231) ~[httpcore-nio-4.4.11.jar:4.4.11] at org.apache.http.impl.nio.codecs.AbstractMessageParser.fillBuffer(AbstractMessageParser.java:136) at org.apache.http.impl.nio.DefaultNHttpClientConnection.consumeInput(DefaultNHttpClientConnection.java:241) at org.apache.http.impl.nio.client.InternalIODispatch.onInputReady(InternalIODispatch.java:81) ~[httpasyncclient-4.1.4.jar:4.1.4] at org.apache.http.impl.nio.client.InternalIODispatch.onInputReady(InternalIODispatch.java:39) at org.apache.http.impl.nio.reactor.AbstractIODispatch.inputReady(AbstractIODispatch.java:114) ~[httpcore-nio-4.4.11.jar:4.4.11] at org.apache.http.impl.nio.reactor.BaseIOReactor.readable(BaseIOReactor.java:162) at org.apache.http.impl.nio.reactor.AbstractIOReactor.processEvent(AbstractIOReactor.java:337) at org.apache.http.impl.nio.reactor.AbstractIOReactor.processEvents(AbstractIOReactor.java:315) at org.apache.http.impl.nio.reactor.AbstractIOReactor.execute(AbstractIOReactor.java:276) at org.apache.http.impl.nio.reactor.BaseIOReactor.execute(BaseIOReactor.java:104) at org.apache.http.impl.nio.reactor.AbstractMultiworkerIOReactor$Worker.run(AbstractMultiworkerIOReactor.java:591) ... 1 common frames omitted Wrapped by: java.io.IOException: Connection reset by peer at org.elasticsearch.client.RestClient.extractAndWrapCause(RestClient.java:793) ~[elasticsearch-rest-client-7.3.2.jar:7.3.2] at org.elasticsearch.client.RestClient.performRequest(RestClient.java:218) at org.elasticsearch.client.RestClient.performRequest(RestClient.java:205) at org.elasticsearch.client.RestHighLevelClient.internalPerformRequest(RestHighLevelClient.java:1454) ~[elasticsearch-rest-high-level-client-7.3.2.jar:7.3.2] at org.elasticsearch.client.RestHighLevelClient.performRequest(RestHighLevelClient.java:1424) at org.elasticsearch.client.RestHighLevelClient.performRequestAndParseEntity(RestHighLevelClient.java:1394) at org.elasticsearch.client.RestHighLevelClient.search(RestHighLevelClient.java:930) at org.springframework.scheduling.support.DelegatingErrorHandlingRunnable.run(DelegatingErrorHandlingRunnable.java:54) [spring-context-5.1.6.RELEASE.jar:5.1.6.RELEASE] at org.springframework.scheduling.concurrent.ReschedulingRunnable.run(ReschedulingRunnable.java:93) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) [na:1.8.0_252] at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$201(ScheduledThreadPoolExecutor.java:180) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:293) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) ``` and could not find any errro logs in elastic ---

Hi @wmj765 The exception you're seeing > [@wmj765](#): > > ```auto > java.io.IOException: Connection reset by peer > > ``` is caused by a forceful connection termination (`RST`). Elasticsearch itself does not RST HTTP connections (or any other connections for that matter) itself. Likely another piece of your network infrastructure (firewall/proxy/switch/router/...) that sits between your client and Elasticsearch is closing the connection here. ---
