Why this happens

The Clerk middleware or auth guard is protecting the wrong paths, including the sign-in or callback routes, so the user gets trapped in a redirect loop.

Fix

Exclude public auth routes from protection

Make sure the middleware does not protect sign-in, sign-up, callback, or other public auth routes.

Regenerate the auth guard in Cursor

Use a prompt that clearly separates public and protected routes.

Copy this prompt

Clerk is causing a redirect loop.
Please update the middleware and auth guard so public auth routes stay public, protected routes require a session, and the app only redirects after Clerk has fully loaded the current user.
