AADSTS500113: No reply address is registered for the application

If you’ve encountered the AADSTS500113 error while using an Azure AD application during authentication, fear not! This blog post will guide you through a quick fix to resolve the issue and get you back on track.

The error code “AADSTS500113: No reply address is registered for the application” in Azure AD (Azure Active Directory) indicates that the application you are trying to authenticate with does not have a valid reply URL registered in its configuration.

The reply URL is the endpoint to which Azure AD will send the authentication response after a successful login. It acts as a callback URL where the user is redirected back to the application with the authentication token. If this URL is missing or incorrect, the authentication process cannot be completed, leading to the mentioned error.

The fix

To fix this issue, you need to ensure that the correct reply URL is registered for the application in Azure AD. Here’s what you can do:

1. Sign in to the Azure portal as an administrator or a user with appropriate permissions.
2. Navigate to “Azure Active Directory” from the left-hand navigation pane.
3. In the Azure AD portal, go to “App registrations” section (on left side of Azure Portal)
4. Search for the specific application that is causing the error and click on it.
5. In the application’s settings, look for the “Authentication” section. (on left side of Azure Portal)
6. Check the “Redirect URIs” settings. Ensure that the URL where your application is hosted or deployed is listed here.
7. If the reply URL is missing or incorrect, add the correct URL for your application. Make sure to include the full path and any query parameters if required as below. Click “Save” or “Update” to apply the changes.

After updating the reply URL, try to authenticate with the application again. The error should be resolved, and you should be able to log in successfully.

By following these quick steps, you should have successfully resolved the AADSTS500113 error. Now your Azure AD application will be equipped with the necessary reply URL, enabling seamless authentication for your users. Remember to verify all required reply URLs for different environments if applicable.

Note that some applications may require multiple reply URLs, especially if they have different environments (e.g., development, staging, production). Ensure all necessary URLs are registered to avoid any future authentication issues. Also, be cautious when making changes to applications used by multiple users, as an incorrect reply URL could impact their ability to sign in.
