❓Redirect URI Mismatch — AADSTS50011 — Trouble with Power BI Embed Flow

Hello Microsoft Community,

I'm building a Power BI embedded web application using the interactive login flow with MSAL (Python), but I keep getting the error AADSTS50011 regarding the Redirect URI mismatch.

🔧 My Setup:

• App name: stonerosetreasury-embed-app

Platform: Python Flask (localhost)

Login Flow: Interactive browser login via MSAL

Redirect URI used in code: http://localhost:5000/getAToken

Redirect URI configured in Azure: I tried:

http://localhost

  `http://localhost:5000`

  
     `http://localhost:5000/getAToken` (now added) ✅
```---
🧾 Error Code:


```yaml
rust
Copy
AADSTS50011: The redirect URI 'http://localhost:5000/getAToken' specified in the request does not match the redirect URIs configured for the application '9c3f11fd-7fce-431e-b2ba-1e915496c3bc'.

📷 Screenshot of authentication settings:

(Attached below — includes platform configuration and URIs)

✅ What works:

Using Service Principal Flow with generate_embed_token.py successfully acquires a token and embed URL.

But I want to support interactive user login (e.g. for accessing user-bound reports).

❓Question:

What else do I need to configure in Azure to make http://localhost:5000/getAToken accepted as a valid redirect URI for my app?

Any advice or checklist I can follow?Hello Microsoft Community,
