When I tried to perform a elasticsearch-plugin install ingest-geoip, I get the following error: Exception in thread "main" javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target at sun.security.ssl.Alerts.getSSLException(Alerts.java:192) at sun.security.ssl.SSLSocketImpl.fatal(SSLSocketImpl.java:1964) at sun.security.ssl.Handshaker.fatalSE(Handshaker.java:328) at sun.security.ssl.Handshaker.fatalSE(Handshaker.java:322) at sun.security.ssl.ClientHandshaker.serverCertificate(ClientHandshaker.java:1614) at sun.security.ssl.ClientHandshaker.processMessage(ClientHandshaker.java:216) at sun.security.ssl.Handshaker.processLoop(Handshaker.java:1052) at sun.security.ssl.Handshaker.process\_record(Handshaker.java:987) at sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:1072) at sun.security.ssl.SSLSocketImpl.performInitialHandshake(SSLSocketImpl.java:1385) at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1413) at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1397) at sun.net.www.protocol.https.HttpsClient.afterConnect(HttpsClient.java:559) at sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.connect(AbstractDelegateHttpsURLConnection.java:185) at sun.net.www.protocol.https.HttpsURLConnectionImpl.connect(HttpsURLConnectionImpl.java:162) at org.elasticsearch.plugins.InstallPluginCommand.urlExists(InstallPluginCommand.java:352) at org.elasticsearch.plugins.InstallPluginCommand.getElasticUrl(InstallPluginCommand.java:314) at org.elasticsearch.plugins.InstallPluginCommand.download(InstallPluginCommand.java:254) at org.elasticsearch.plugins.InstallPluginCommand.execute(InstallPluginCommand.java:229) at org.elasticsearch.plugins.InstallPluginCommand.execute(InstallPluginCommand.java:216) at org.elasticsearch.cli.EnvironmentAwareCommand.execute(EnvironmentAwareCommand.java:86) at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:124) at org.elasticsearch.cli.MultiCommand.execute(MultiCommand.java:77) at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:124) at org.elasticsearch.cli.Command.main(Command.java:90) at org.elasticsearch.plugins.PluginCli.main(PluginCli.java:47) Caused by: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target ``` at sun.security.validator.PKIXValidator.doBuild(PKIXValidator.java:397) at sun.security.validator.PKIXValidator.engineValidate(PKIXValidator.java:302) at sun.security.validator.Validator.validate(Validator.java:262) at sun.security.ssl.X509TrustManagerImpl.validate(X509TrustManagerImpl.java:324) at sun.security.ssl.X509TrustManagerImpl.checkTrusted(X509TrustManagerImpl.java:229) at sun.security.ssl.X509TrustManagerImpl.checkServerTrusted(X509TrustManagerImpl.java:124) at sun.security.ssl.ClientHandshaker.serverCertificate(ClientHandshaker.java:1596) ... 21 more ``` Caused by: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target at sun.security.provider.certpath.SunCertPathBuilder.build(SunCertPathBuilder.java:141) at sun.security.provider.certpath.SunCertPathBuilder.engineBuild(SunCertPathBuilder.java:126) at java.security.cert.CertPathBuilder.build(CertPathBuilder.java:280) at sun.security.validator.PKIXValidator.doBuild(PKIXValidator.java:392) ... 27 more ---

Are you using SSL encryption and authentication for Elasticsearch? What commands did you execute to install / enable the geo-ip plugin? It's also helpful if you post your `elasticsearch.yml` configuration file. ---

Everytime I'm seeing this error, the cause is a broken installation of Java. May be reinstall Java? ---

I just installed everything but haven't updated the elasticsearch.yml file. So that file is the same as the original. As for the commands, I'm doing it from a command prompt in windows 10: elasticsearch-plugin install ingest-geoip I'm not using ssl encryption or authentication for elastic search. I just installed it on my windows 10 desktop. I've also installed Kibana, logstash and filebeat on the same host. I plan on installing this on a linux machine in the AWS cloud but wanted to perform my install on my windows desktop 1st to familiarize myself with the software. ---

I reinstalled java already and got the same results. I have jdk and jre 1.8.0\_181 ---
