Flag sign-in errors for review: Enable flagging

If you plan on getting help for this problem, enable flagging and try to reproduce the error within 20 minutes. Flagged events make diagnostics available and are raised to admin attention.

I've seen that it's related to redirect URL, and we do have the correct URL in our Application:

Here's the redirectURL passed in the config object:

redirectUri: 'http://localhost:3000/'

Not sure what else to try to fix this....

Hi @Tim Anderson
Thank you for reaching Microsoft Q&A Forum!
The Entra ID error AADSTS9002325 may occur when you change your Entra ID app registration's redirect URL to a Single Page Application (SPA). from the Screen shot I can see you have used Single Page Application. changed the registered app to Web and see if the issue is fixed.
