How to fix “AADSTS500113: No reply address is registered for the application” error?

This article describes how to fix the error “AADSTS500113: no reply address is registered for the application”. You typically get this error, when your app is trying to authenticate your users against Azure Active Directory.

I’ve been posting about different versions of Azure Active Directory authentication errors (different errors with AADSTS -codes) a lot – I’ll need to find a better way to categorize them in the future. But, for now, on to the issue!

Problem

Another day, another app, another reply address -related authentication issue in Azure AD. This one (for once) should be simple.

When you’re loading your app, that’s authenticating against Azure AD, most likely in web browser or other online client, you’ll be redirected to a Microsoft Online login page with the following error:

AADSTS500113: no reply address is registered for the application

This error code is kinda peculiar. It’s not listed on Microsoft’s long list of AADSTS-error codes… Perhaps, because it seems to be a variant of AADSTS50011, which itself has a number of different error messages. These error messages describe different issues with reply URLs – just like this particular error code. I don’t know why, but apparently Microsoft thought that the misconfiguration (not to have reply URLs at all!) deserves a custom error code! It basically looks like “error code AADSTS50011, variant 3” – this just makes me wonder what happened to variants 0, 1 and 2…

Okay, but on to the resolution of the issue. What to do?

Solution to error AADSTS500113

Okay, so you need to add a reply URL. Easy? It should be! Let’s see:

How to verify that your reply URL is included in the Redirect URIs of your app:

1. Browse to https://aad.portal.azure.com
2. Log in using your Office 365 / Cloud App Administrator account
3. Navigate to “App registrations”
4. Find your app under “Owned applications” or “All applications”
5. Select “Manage” -> “Authentication”
6. Check the “Redirect URIs” -section. Verify, that the URL you’re accessing the app from really is listed there!

When accessing the Authentication settings under your app registration, you should add the URLs you expect your app to be called from – like in the screenshot below:
