Environment: simulated cluster by using kcli (1 ctrl node + two worker nodes)

Dashboard (when opened in a browser) just keeps loading and doesn't show up. From inside the cluster when doing a curl on the url I can see that sometimes it returns the html content, otherse it just redirects to the the URL.
