Hi! I'm trying to connect to a remote Elasticsearch instance; to do so, I have to tunnel my traffic through a socks5 proxy. In my Java code, I'm using the `ElasticsearchTemplate` which in turn uses a `PreBuiltTransportClient`, but I can't find how to set up a proxy for the connection. There seem to be ways to set a proxy when using the `RestClient` (as described [here](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/master/java-rest-low-usage-initialization.html)) but I don't see how that would be used with the `ElasticsearchTemplate`. Maybe that's the wrong idea anyway. Any hints? Thanks! ---

I don't have the answer for this TBH. May be it's just a `JAVA_OPTS` thingy that you need to set. Like explained for our plugin manager: [https://www.elastic.co/guide/en/elasticsearch/plugins/current/\_other\_command\_line\_parameters.html#\_proxy\_settings](https://www.elastic.co/guide/en/elasticsearch/plugins/current/_other_command_line_parameters.html#_proxy_settings) ```auto JAVA_OPTS="-Dhttp.proxyHost=host_name -Dhttp.proxyPort=port_number -Dhttps.proxyHost=host_name -Dhttps.proxyPort=https_port_number" ``` But anyway, it's not recommended anymore to use the TransportClient as it will be deprecated then removed in the future. You should switch to the HighLevel Rest client. I hope this can help. May be @spinscale has other ideas regarding the proxy settings for Transport Client? ---

No, we dont support anything in the `TransportClient` for that. Even though java has native system properties for socks named `socksProxyHost`and `socksProxyPort` I have never tried this and we do not test for this in our code. On top of trying the above system properties you try could use `ssh` or another socks proxy (not sure if `stunnel` can do this) to create a socks tunnel and then point the transport client to that one. I think however that this will result in problems when publish addresses from the cluster state are read and not reachable, so routing is pretty important (and tricky!) here. I am unsure if this will work at all, TBH. --Alex ---

Thanks for the feedback, we've switched to the HighLevel client. However, that only seems to allow setting an HTTP proxy rather than a SOCKS5 proxy. What I'm trying is the following: ```java public RestHighLevelClient restClient() { RestClientBuilder builder = RestClient.builder(new HttpHost(esHost, esPort, "http")); builder.setHttpClientConfigCallback( httpAsyncClientBuilder -> httpAsyncClientBuilder.setProxy(new HttpHost(proxyHost, proxyPort)) ); return new RestHighLevelClient(builder.build()); } ``` Every time I then try to access the Elasticsearch instance I get this exception: ```auto org.apache.http.ConnectionClosedException: Connection closed at org.apache.http.nio.protocol.HttpAsyncRequestExecutor.endOfInput(HttpAsyncRequestExecutor.java:347) ~[httpcore-nio-4.4.9.jar:4.4.9] at org.apache.http.impl.nio.DefaultNHttpClientConnection.consumeInput(DefaultNHttpClientConnection.java:261) ~[httpcore-nio-4.4.9.jar:4.4.9] at org.apache.http.impl.nio.client.InternalIODispatch.onInputReady(InternalIODispatch.java:81) ~[httpasyncclient-4.1.3.jar:4.1.3] at org.apache.http.impl.nio.client.InternalIODispatch.onInputReady(InternalIODispatch.java:39) ~[httpasyncclient-4.1.3.jar:4.1.3] at org.apache.http.impl.nio.reactor.AbstractIODispatch.inputReady(AbstractIODispatch.java:114) ~[httpcore-nio-4.4.9.jar:4.4.9] at org.apache.http.impl.nio.reactor.BaseIOReactor.readable(BaseIOReactor.java:162) ~[httpcore-nio-4.4.9.jar:4.4.9] at org.apache.http.impl.nio.reactor.AbstractIOReactor.processEvent(AbstractIOReactor.java:337) ~[httpcore-nio-4.4.9.jar:4.4.9] at org.apache.http.impl.nio.reactor.AbstractIOReactor.processEvents(AbstractIOReactor.java:315) ~[httpcore-nio-4.4.9.jar:4.4.9] at org.apache.http.impl.nio.reactor.AbstractIOReactor.execute(AbstractIOReactor.java:276) ~[httpcore-nio-4.4.9.jar:4.4.9] at org.apache.http.impl.nio.reactor.BaseIOReactor.execute(BaseIOReactor.java:104) ~[httpcore-nio-4.4.9.jar:4.4.9] at org.apache.http.impl.nio.reactor.AbstractMultiworkerIOReactor$Worker.run(AbstractMultiworkerIOReactor.java:588) ~[httpcore-nio-4.4.9.jar:4.4.9] at java.lang.Thread.run(Thread.java:745) [?:1.8.0_121] ``` When leaving out the proxy settings (`builder.setHttpClientConfigCallback(...)`) and connecting to an instance that does not require a proxy, no problem. We do have a workaround, but getting it to run without that would be great. ---
