When you integrate a Qlik Sense object into an application like SharePoint, you need to have consistent connections; whether you use an HTTP or HTTPS on both sides of Qlik Sense and SharePoint.
Environment
If you use an HTTPS connection, a third-party SSL certificate needs to be configured.
If you prefer an HTTP connection, tick the box of Allow HTTP in QMC> Proxies.
