Hi, It is most likely because of the communication occurring via an HTTP server, not an HTTPS server. Here, you are trying to connect a non SSL enabled client with an SSL enabled source. In order to enable or disable HTTPS in Denodo Platform, you can utilize the [Denodo TLS Configurator](https://community.denodo.com/docs/html/browse/8.0/en/platform/installation/postinstallation_tasks/enable_ssl_connections_in_the_denodo_platform_servers/denodo_tls_configurator_script) script if you are on Denodo 8.0. The Denodo TLS Configurator script automates the process of enabling SSL in all the modules of the Denodo Platform and the Solution Manager, including the web container. Note: If you are using an older version of the Denodo Platform, the above shared link is not applicable. For Denodo 7.0, please refer [here](https://community.denodo.com/docs/html/browse/7.0/platform/installation/postinstallation_tasks/enable_ssl_connections_in_the_denodo_platform_servers/enable_ssl_connections_in_the_denodo_platform_servers). Hope this helps!
