Hi Richard! It seems you’re on pages that are not part of the course. Hence, those errors.
In the Vocareum page (i.e. the same page where you see the timer is counting down), there are instructions on what to search for and screenshots from AWS. For example, here are steps 3 and 4 which pertains to what service you should navigate to.
I checked the lab and it seems to be working fine for me. I am not being redirected to Sagemaker Canvas. Also checked recent reports and don’t find a redirection issue as of now. They are related to other issues that are mostly addressed in the FAQ. If that persists on your account, just let us know and we can look into it. Thank you.
