How to Fix “Auth Redirect Loop” in Clerk (2026 Guide) The Short Answer To fix the “Auth Redirect Loop” error in Clerk, advanced users can try toggling the “Auth Redirect” option to Off in the Settings > Authentication > Advanced menu, and then refresh the page. This quick fix resolves the issue in most cases, but for a more permanent solution, configuring the middleware settings is necessary.
