DA100 Lab 02 Having Trouble Signing you in error message, in the middle of the lab

Copper Contributor

I'm able to start and use lab 02, but after a couple of minutes, I get a dialog saying Leave Site? Changes you made may not be saved, which reappears countless times and locks up my browser session. Once I finally get the lab to end, there's more info on a Sign In page that is presented:


Sorry, We're having trouble signing you in


AADSTS50196: The server terminated an operation because it encountered a client request loop. Please contact your app vendor. 


I'd really like to continue this lab. Is there a fix or a workaround?

I am getting the same error in that Lab

This problem occurred in Chrome. The lab works fine when using Microsoft Edge
