Hi Admin,

This is Tuan - developer of my team.
We are using AzureAD for login flow but we got the error 401 unauthorized for https://autologon.microsoftazuread-sso.com.
Could you please help to give some advice to bypass it?
Although it doesn't block any flow but i represent my team to investigate that.
My appreciate for your support.


Thanks in advance,
