Hello, I’ve been doing GitOps at Scale course, but after I came to first excercise (Live exercise: app of apps), I found out that the environment is not working. I do not see any shell or argo ui. On firefox I’ve seen an auth error and then empty screens. On Brave there is an error message displayed.

Error shown in Brave:

Sorry I need to put there multiple replies to embed the screenshots (because of new user policy)
