seems like https : bireporting.xxxxx.com is loadbalancer/F5 url.
when we use loadbalancer/F5 In BO, there are two ways to enable SSL.
1) in the Tomcat nodes: SSL needs to be enabled in the Tomcat host and you will be able to find all the ports and certificate details in server.xml. Redirection you will be able to see it in index.html
2) In loadbalancer/F5 url: SSL will be done loadbalancer/F5 url. there is nothing to do from BO web server side. For that you can check with the respective loadbalancer/F5 team.
