Azure Active Directory with AWS Cognito redirect to login live 404

Question

Hello,

I configured an Azure Active Directory with an AWS Single Sign on throught aws cognito saml2.

I put my Azure Active Directoy as a IDP in Aws Cognito.

When i try to sign in for first time, i m redirected to a page login.live with a 404 response without explication.

But if im already connected on my Account Azure, and i that i try again to login i m correctly redirect to the app when i try to single sign on.

Here is the link that i use to connect : https://xxxxxxxx.auth.eu-west-1.amazoncognito.com/login?client_id=xxxxxxxxxxxxd&response_type=code&scope=email+openid&redirect_uri=xxxxxxxxxxxxxxxxxxxxxxxx

I followed this tutorial : https://www.terminalbytes.com/azure-ad-integration-as-an-idp-with-aws-cognito/
