CAPTCHA loop — Endless CAPTCHA — solving it changes nothing

You solve the challenge and get another one. The challenge is not really asking you to prove humanity — the system already decided, and the loop is what a low score looks like from the outside.

A proxy fixes part of this. Better IP reputation raises the score that caused the loop, which often ends it. If the loop survives a clean IP, the problem is your client and no pool will fix it.

Why it happens

The IP reputation is bad enough that no solve will clear it.

The cookie that records the solve is not being persisted, so each request starts again.

The fingerprint marks the client as automation regardless of the solve.

Cookies are being sent to the wrong domain, so the solve is recorded and then never presented.

How to fix it

  1. Check the cookie jar first — a loop with a working solve is usually a persistence bug, not a detection one.
  2. Move to a cleaner pool: residential and mobile exits start at a much higher score.
  3. Fix the fingerprint before spending money on solves. A loop means the solve is not the constraint.
