I have configured Azure AD multi-tenant autentication by following this article: https://docs.microsoft.com/en-us/azure/active-directory-b2c/identity-provider-azure-ad-multi-tenant-custom?tabs=applications
The authentication worked on friday last week, but now its suddenly failing. I tried to re-register the application in Azure AD with new App Id and new App secret that was added in both ends.
Error i'm getting:
Sorry, but we’re having trouble with signing you in. AADSTS9002325: Proof Key for Code Exchange is required for cross-origin authorization code redemption.
Am I overlooking something obvious?
Authentication is used with a SPA Web App using React with react-aad-msal
