Entra Integration Authentication issue with 401 Error

[erg-hzhou]

• Integrated Entra ID authentication with this App (customized with out own data) at the tenaent level, it works fine until recently. After a user entered their crediental (office 365 login), it poped up login screen 3~4 times then the users got 401. (set AZURE_USE_AUTHENTICATION="true" in .env)

• The URL address from the browser is (containerApp) as below:

• https://redacted.eastus.azurecontainerapps.io/.auth/login/aad/callback .

• Any clue? How to reslove it?

@erg-hzhou Did you recently bring in changes to your copy of the repo, or did you start seeing errors despite not making any changes?
Do you see any JS errors in the console when this happens? Sometimes MSAL.JS logs out more details to the console about errors.

@pamelafox Thank you very much for the quick reply. Here is what I did to solve the issue. I went to Azure Portal and deleted both search azure chat server and search azure chat client registration via App Registrations. After that, I used "Azd Up" to redeploy the App. It worked. I am not sure it was caused by Azure cloud outage last week.
