Question

AADSTS500113: No reply address is registered for the application - testing application on local computer

ProgrammerBret 6

I am testing my Blazor application on my local computer, running visual studio 2019. I am working with IT to test the Azure AAD authentication. When I use developer tools, I see that I am using port 44372, so I added the route "https://localhost:44372/signin-oidc" to the redirect URL section in AAD. However the message AADSTS500113 is still present.
In the appsentings.json file, it looks like this:

  "AzureAd": {
    "Instance": "https://login.microsoftonline.com/",
    "Domain": "ApplicationName.com",
    "TenantId": "20d9a065-80de-46c0-a30e-4ef4dedf70c68",
    "ClientId": "c7992cff-f985-4e6e-80d6-08300fe53rfc",
    "CallbackPath": "/signin-oidc"
  },

Hi -- Thanks for the reply. In that post, does that fact that they are using http vs https make a difference? I have been working with IT department as I do not have access to the AAD portal. We have indeed added the following redirect URI's in this field but to no avail:

https://localhost:5001
https://localhost:5001/signin-oidc

I don't know if the "Domain" field in the appsettings.json is relevant. As far as I can tell it is to be the FQDN of the application. I can confirm that the TenantID and Client ID match. When I run the application from Visual Studio, is uses port 44371, but I have since learned that the default IIS express port is 5001.
I can't seem to find documentation on the learn.microsoft.com pages for AAD with Blazor server using .net 5.0 on the latest version of Visual Studio 2019.
