404-Error in SharePoint add-in

Hi.
For testing I installed the Matomo-SharePoint add-in from Download SharePoint Analytics - Analytics Platform - Matomo .

However, after having installed the add-in in one Site, after clicking the “SharePoint Site Collection Analytics By Matomo”-Icon I see some page loading and then I get redirected quickly to https://sharepoint-analytics.azurewebsites.net/SharePointSiteCollectionAnalyticsByMatomo/Pages/Configuration.aspx?SPHostUrl=https://********.sharepoint.com/sites/matomo-test&SPAppWebUrl=undefined which results in a 404-Error.

I followed the installation exactly. Is there something more I need to do?
