Elastic search not getting executed with Https

I've generated the certiificate using the command

keytool -genkey -alias tomcat -keyalg RSA -keystore D:\keyPath\key and added the same in the server.xml in apache/conf.

     <Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol" SSLEnabled="true"
           maxThreads="150" scheme="https" secure="true"
           clientAuth="false" sslProtocol="TLS" sslEnabledProtocols="TLSv1,TLSv1.1,TLSv1.2"
           keyAlias="tomcat" />

Now the https request is loading the web page but the elasticsearch queries not getting executed. Could you please tell me what configuration change to be made in the elastic search to get the https request working.

Getting the following error .

Failed to load resource: net::ERR_CONNECTION_CLOSED https://localhost:9200/?hello=elasticsearch
