Your app was expected to throttle the subsequent requests, and only retry after the specified period. MSAL Python 1.16+ makes it easy for you to retry an authentication request on-demand (for example, whenever the end-user clicks the sign-in button again), MSAL Python 1.16+ would automaticall...

We will demonstrate how to handle this case by setting thetimeoutparameter in therequests.get()method to an extremely small number; this will raise an error, and we will handle that error using therequests.Timeoutobject. The most straightforward workaround for timeout errors is to set longer...
