Hello victor francis,

Hey Victor! It sounds like you're facing a CORS issue while trying to make a network request, and that the error message suggests checking the redirectUri in the Azure App Portal. Here’s what you can do to potentially resolve this issue:

Check the redirectUri: Ensure that the redirectUri you are using in your application is correctly registered in the Azure App Portal. It should be listed under the settings for your application and must be of type 'SPA' (Single Page Application).

Verify CORS settings: If you're working with a web application, ensure that CORS is properly configured on your server to allow requests from the origin where your app is running.

Inspect your browser options: Since this error might be related to browser behavior, particularly in Chrome, you can refer to this article for troubleshooting tips.

Authentication policies: Double-check your authentication policies to ensure they don't inadvertently block the required requests.

If the issue persists after following these steps, consider checking relevant log headers and network details to gather more information about what might be causing the rejection of the request.

Follow-up Questions:

Can you confirm which application type you are working with (web app, mobile app, etc.)?

Could you provide the exact redirectUri you are using?

Are there any specific browser settings that may be interfering with the request?

Have you checked other applications in the same Azure tenant for similar settings?

Hope this helps you get closer to resolving your issue!
