Root Cause

Middleware redirects to a URL that triggers the middleware again, causing infinite loop.

generic

Workarounds

  1. 95% success Add matcher config to exclude the redirect destination from middleware 
    export const config = { matcher: ['/((?!login|_next|api|static).*)'] };

    Sources: https://nextjs.org/docs/app/building-your-application/routing/middleware#matcher

  2. 92% success Check for the redirect destination in the condition: if (url !== '/login') redirect('/login') 
    if (url !== '/login') redirect('/login')

    Sources: https://nextjs.org/docs/app/building-your-application/routing/middleware

Dead Ends

Common approaches that don't work:

  1. Add a redirect counter in cookies 75% fail

    Over-engineering — fix the matcher config instead

  2. Disable the middleware temporarily 70% fail

    Doesn't fix the issue — it'll come back when re-enabled
