Hi @MSK1116

Welcome to the Auth0 Community!

You can check out [this community post](https://community.auth0.com/t/cors-error-with-quarkus-backend-and-nextjs-frontend/170021/3) regarding the CORS error that you are receiving.

As the solution mentions, it happens because the login is being served on a different origin than the one requesting it. In these scenarios, you must include the origin to your **Allowed Web Origins** and include your app’s origin URL in the **Allowed Origins (CORS)** of your application settings.

I would also recommend reading through our documentation about [Configuring Cross-Origin Resource Sharing.](https://auth0.com/docs/get-started/applications/set-up-cors).

Let me know if you have any other questions!

Kind Regards,  
Nik
