It’s difficult to pinpoint the exact issue from the description provided. It seems like you are facing an authorization problem when your React frontend communicates with the FastAPI backend during the login process and token handling. To assist you better, could you provide more details about the error or the setup? Sharing a cURL command that replicates the failing request, or screenshots of the error, would be particularly helpful in diagnosing the problem.

Thanks!
