Hi , I have installed a new elasticsearch from scratch and configured and running . after the configuration I have installed the x-pack when it finished I've tried to run it but I got this exception : [2017-08-15T16:14:44,012][ERROR][o.e.b.Bootstrap] Exception org.elasticsearch.ElasticsearchException: Failed to load plugin class [org.elasticsearch.xpack.XPackPlugin] at org.elasticsearch.plugins.PluginsService.loadPlugin(PluginsService.java:434) ~[elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.plugins.PluginsService.loadBundles(PluginsService.java:387) ~[elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.plugins.PluginsService.(PluginsService.java:140) ~[elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.node.Node.(Node.java:312) ~[elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.node.Node.(Node.java:244) ~[elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.bootstrap.Bootstrap$5.(Bootstrap.java:232) ~[elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:232) ~[elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:351) [elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:123) [elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.bootstrap.Elasticsearch.execute(Elasticsearch.java:114) [elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.cli.EnvironmentAwareCommand.execute(EnvironmentAwareCommand.java:67) [elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:122) [elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.cli.Command.main(Command.java:88) [elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:91) [elasticsearch-5.5.1.jar:5.5.1] at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:84) [elasticsearch-5.5.1.jar:5.5.1] Caused by: java.lang.reflect.InvocationTargetException at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) ~[?:?] at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:88) ~[?:?] at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:57) ~[?:?] at java.lang.reflect.Constructor.newInstance(Constructor.java:437) ~[?:1.8.0] at org.elasticsearch.plugins.PluginsService.loadPlugin(PluginsService.java:423) ~[elasticsearch-5.5.1.jar:5.5.1] ... 14 more Caused by: java.lang.IllegalArgumentException: none of the ciphers [TLS\_ECDHE\_RSA\_WITH\_AES\_128\_CBC\_SHA256, TLS\_ECDHE\_ECDSA\_WITH\_AES\_128\_CBC\_SHA256, TLS\_ECDHE\_ECDSA\_WITH\_AES\_128\_CBC\_SHA, TLS\_ECDHE\_RSA\_WITH\_AES\_128\_CBC\_SHA, TLS\_RSA\_WITH\_AE S\_128\_CBC\_SHA256, TLS\_RSA\_WITH\_AES\_128\_CBC\_SHA] are supported by this JVM at org.elasticsearch.xpack.ssl.SSLService.supportedCiphers(SSLService.java:355) ~[?:?] at org.elasticsearch.xpack.ssl.SSLService.createSslContext(SSLService.java:388) ~[?:?] at org.elasticsearch.xpack.ssl.SSLService.loadSSLConfigurations(SSLService.java:401) ~[?:?] at org.elasticsearch.xpack.ssl.SSLService.(SSLService.java:79) ~[?:?] at org.elasticsearch.xpack.XPackPlugin.(XPackPlugin.java:205) ~[?:?] at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) ~[?:?] at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:88) ~[?:?] at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:57) ~[?:?] at java.lang.reflect.Constructor.newInstance(Constructor.java:437) ~[?:1.8.0] at org.elasticsearch.plugins.PluginsService.loadPlugin(PluginsService.java:423) ~[elasticsearch-5.5.1.jar:5.5.1] ... 14 more [2017-08-15T16:14:44,031][WARN][o.e.b.ElasticsearchUncaughtExceptionHandler] [STG\_ELK\_TEST01] uncaught exception in thread [main] org.elasticsearch.bootstrap.StartupException: ElasticsearchException[Failed to load plugin class [org.elasticsearch.xpack.XPackPlugin]];

See this message in your stack trace. ```auto none of the ciphers [TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA, TLS_RSA_WITH_AE S_128_CBC_SHA256, TLS_RSA_WITH_AES_128_CBC_SHA] are supported by this JVM ``` What JVM are you running on? Please paste the output of `java -version` You can also just try with the oracle JDK and check if the error message stays. Make sure you are also exporting `JAVA_HOME` when switching JVMs. ---

Hi, I thought that the issue , so I have removed the default java that was installed with OS and download a new version from oracle site and issue have been solve. Thanks, ---

Out of curiosity, which JVM were you using before that? Was it a package from the operating system? And on which distribution/which version? ---

I have used this version java-1.8.0-ibm from our local yum repository. ---

Is this suse? Can you paste the output of `java -version` before you installed another JVM? That would help tremendously to figure out if we should add some notes to our documentation for a certain linux distribution. Thanks so much! ---
