AADSTS50011: The redirect URI 'https://usnconeboxax1aos.cloud.onebox.dynamics.com/' specified in the request does not match the redirect URIs configured for the application '00000015-0000-0000-c000-000000000000'. Make sure the redirect URI sent in the req

AADSTS50011 means the redirect URI sent by the application does not exactly match a redirect URI configured in the Microsoft Entra app registration.

For this error, compare the URI in the error message:

https://usnconeboxax1aos.cloud.onebox.dynamics.com/

with the redirect URIs configured for application ID 00000015-0000-0000-c000-000000000000 in Microsoft Entra ID.

Use this path:

1. Open Microsoft Entra ID.
2. Go to App registrations.
3. Find the application by the application ID from the error.
4. Open Authentication under Manage.
5. Under Redirect URIs, add or correct the exact URI shown in the error.

Important checks:

• The match must be exact.
• Check HTTP vs HTTPS.
• Check trailing slash differences.
• Check path differences.
• Check port differences.
• Check case sensitivity in the URL path.
• If a reverse proxy or load balancer is involved, verify it is not rewriting the redirect URI.
• If the URI being sent is not the intended one, update the application configuration or code instead of only changing the app registration.

If this is a dev/test/prod split, add each required environment-specific redirect URI separately.
