Several issues with the lab 4-exercise-use-shared-access-signatures

Question

I had several issues to complete the exercise 4-exercise-use-shared-access-signatures (https://learn.microsoft.com/en-us/training/modules/control-access-to-azure-storage-with-sas/4-exercise-use-shared-access-signatures).

First I had to migrate the project cloned from hxxps[://]github[.]com/MicrosoftDocs/mslearn-control-access-to-azure-storage-with-sas[.]git from .NET SDK 7.0.400 to the version installed on the sandbox vm 8.0.4 then I was able to run it, but then trying to access the app from my browser with the returned URL (hxxps[://]ux[.]console[.]azure[.]com/proxy/8001/) I get this error: "The resource you are looking for has been removed, had its name changed, or is temporarily unavailable."

So I wasn't able to complete the task.
