I apologize if my description doesn't include enough information. I am new to azure, and this is the first project I am working on using b2c.
The problem I am having is regarding logging a user in with b2c. When I log in locally there is no issue. We are directed to the login page, and it signs in successfully. 209992-auth1.png

When we deploy the application on azure, and we go to sign in. We are met with this instead 209942-auth2.png

We know very little about this kind of this, but from what I can tell we were thinking that it may have to do with the redirecturl in the b2c tenent. Any help at all would be greatly appreciated.

    Hello @Preston Checkan , the error you're facing is caused by the lack of the client_id query parameter in your authentication URL. Ensure your application configuration contains the required values for the aforementioned and other required parameters. Take a look to this document for how to configure an ASP.NET Core application.

    If you're using Azure Web Apps please take a look to Configure an App Service app.

    For more information about error codes take a look to Error codes: Azure Active Directory B2C.
