Provided by Let's Encrypt, Cloudbric issues free SSL certificates for all websites. This will guarantee encrypted communications between users (client) and Cloudbric (server). So, if you want HTTPS (https://) in front of your domain address while your website is being protected by Cloudbric, then you need to have an SSL certificate at our (Cloudbric) server as well.
For users who prefer maintaining their own SSL, they may upload their custom SSL from the console. Go to Settings, SSL/Redirect, SSL Type, then select Custom SSL.
