By default, only HTTP protocol is configured during the PPM installation. HTTPS is disabled as you need a valid certificate for the load balancer. Perform the following steps to enable HTTPS.
Create your own certificate for your server and have it signed by an official certification authority (CA). See PPM Operation Guide for details.
Enhance the load balancer with this certificate. The certificate consists of two files (a key and a crt file) packed into a zip archive. The ARIS PPM Cloud Controller command looks like this: enhance loadbalancer_x with sslCertificate local file "<path to ZIP file>"
Finally enable HTTPS protocol and make it the default protocol that should be used: reconfigure loadbalancer_x +HTTPD.ssl.port=4443 reconfigure loadbalancer_x +zookeeper.application.instance.port=4443 reconfigure loadbalancer_x +zookeeper.application.instance.scheme=https
The given port is the default HTTPS port used in PPM installation and loadbalancer_x represents the load balancer ID.
