I have successfully installed SSL certificate and restarted the elasticsearch instance. Then while I'm running this query ` curl -k http://localhost:9200?pretty -u elastic` I'm getting this error ` curl: (35) error:1408F10B:SSL routines:ssl3_get_record:wrong version number` ---

Hi Kartheek, First please try [https://localhost:9200](https://localhost:9200) and add the -v parameter to the curl command and post the output. Also you can check the ssl-cert with the following command: > openssl x509 -in certificate.crt -text -noout Regards, Simon ---
