Whenever I start up ES by running ES .bat file on Windows, I receive this error:

[ERROR][o.e.b.Elasticsearch] [node-1] fatal exception while booting Elasticsearchorg.elasticsearch.ElasticsearchSecurityException: invalid configuration for xpack.security.transport.ssl - [xpack.security.transport.ssl.enabled] is not set, but the following settings have been configured in elasticsearch.yml : [xpack.security.transport.ssl.keystore.secure\_password,xpack.security.transport.ssl.truststore.secure\_password] at org.elasticsearch.xcore@8.9.1/org.elasticsearch.xpack.core.ssl.SSLService.validateServerConfiguration(SSLService.java:650) at org.elasticsearch.xcore@8.9.1/org.elasticsearch.xpack.core.ssl.SSLService.loadSslConfigurations(SSLService.java:624) at org.elasticsearch.xcore@8.9.1/org.elasticsearch.xpack.core.ssl.SSLService.(SSLService.java:159) at org.elasticsearch.xcore@8.9.1/org.elasticsearch.xpack.core.XPackPlugin.createSSLService(XPackPlugin.java:495) at org.elasticsearch.xcore@8.9.1/org.elasticsearch.xpack.core.XPackPlugin.createComponents(XPackPlugin.java:324)

How can I resolve this?

Hi @sanyam,

Can you try setting the `xpack.security.transport.ssl.enabled` option in your configuration?
