When I tried to enable SSL for the embedded Web Container, I was able to configure it successfully. Hence, I would suggest you to verify the steps followed to configure SSL in the Embedded Web Container by referring the [Enabling HTTPS in the Embedded Apache Tomcat](https://community.denodo.com/docs/html/browse/latest/en//platform/installation/postinstallation_tasks/enable_ssl_connections_in_the_denodo_platform_servers/enabling_https_in_the_embedded_apache_tomcat#enabling-https-in-the-embedded-apache-tomcat) documentation.
Also, after enabling SSL in your embedded Apache Tomcat, the protocol used in the URL would be HTTPS and not HTTP. So, you would need to use the below URL to access the Denodo RESTful WS,
Hope this helps!!
