Why Am I Getting CAPTCHAs on Every Site? Causes and Fixes

Constant CAPTCHAs almost always trace back to your network route, your browser settings, or the two disagreeing with each other. The causes in order of how common they are, with a fix for each.

Constant CAPTCHAs usually mean one thing. Something about the way you arrive at a site looks like a machine, or looks like a crowd sharing one door, and the site has raised the cost of entry until it gets a clearer signal. The check is the symptom. The cause sits in your network route, in your browser settings, or in the two of them telling a site different stories.

Work through the causes below in order. The first three are far and away the most common, and they all live in the same place: the address your traffic arrives from.

Start with the address, because that is usually it

The address is shared, or it has history

Most connections do not give you an address of your own. Mobile carriers and many home providers put large numbers of subscribers behind a small pool of public addresses. Offices, campuses and coworking spaces do the same. Whatever anybody else behind that address did this morning, you inherit this afternoon.

Cheap proxy pools work the same way with worse odds. A shared residential pool rents the same address to whoever is buying that hour, and a site that saw a wave of sign-in attempts from it earlier is going to be careful about the next one.

The fix starts with finding out what address you are actually presenting, then testing it rather than trusting the description you were sold. In PowerOps a proxy is added to a library and tested before it goes anywhere near an account, and the test reports the address that was observed. If the route turns out to be shared, move the profile onto one that is not.

It is a datacentre address

Address ranges belonging to hosting providers are published, catalogued and trivial to look up. Nothing is wrong with a datacentre address in itself, and a great deal of ordinary traffic comes from one. For a signed-in consumer account it is an unusual place to be sitting, and sites weigh it accordingly.

The fix is to keep datacentre addresses for work that involves no personal login, and use residential or mobile addresses for account sessions. Cost goes up. Friction goes down. That trade is the whole decision.

You are on a VPN exit that everybody uses

A consumer VPN concentrates an enormous number of people onto a handful of exit addresses. That is the product working as designed. It is also why a session behind one collects checks it collects nowhere else. Nothing you did put that address under scrutiny. Sheer volume did.

The fix is a route of its own per profile, from a provider that sells sticky addresses. If you need a VPN for something unrelated, keep it off the machine or the profile doing account work, and never stack it on top of a proxy.

The address changes in the middle of a session

Rotating endpoints hand you a new address per request or per interval. For collecting public data that is useful. For a signed-in session it is a problem you created for yourself. A session that starts in one city and continues from another a few minutes later describes something no person does.

This cause has a distinctive shape. The first few minutes are clean. Then checks appear on every navigation, often with a surprise sign-out somewhere in the middle of it.

The fix is to switch the endpoint to a sticky or session-persistent mode, with a hold time longer than your working session. Assign the route before the first sign-in, because the first session is the one that establishes what normal looks like for that account.

Then check whether the browser is telling a consistent story

Timezone, language and address disagree

A profile routed through Frankfurt that reports a Los Angeles timezone has answered the same question two different ways. So has one presenting a Brazilian address alongside a browser language list that contains only Vietnamese. Neither value is remarkable on its own. Together they are the cheapest contradiction a site can look for.

The fix is to set the profile's timezone and language list to match the country its route lands in, and to check them together after every route change. This is the most common self-inflicted cause on the list and it takes about ten seconds to correct.

The request rhythm looks automated

Page loads at exactly four second intervals. Forms filled instantly with no focus events in between. Navigation with no scrolling anywhere. A dozen profiles doing identical things in the same second from the same subnet. None of that is forbidden. All of it is unusual, and unusual is what raises the cost of entry.

The fix is pacing. Stagger profile starts instead of launching everything at once. Give scripted work variable delays and let pages settle before the next action. Run smaller batches. If a script is moving through a site faster than a person could, the site is entitled to ask who is on the other end.

Then look at what the browser keeps and what it blocks

The cookie set is stale, missing, or thrown away nightly

Most checks record their own result. Pass one and the site stores something that says this browser already answered, and the check stops appearing for a while. Clear cookies on every exit, browse in a private window, or spin up a fresh temporary profile each time, and that record goes in the bin at the end of every session. The next visit starts cold.

The fix is a profile with a persistent directory of its own, closed properly so its state is written out. A profile killed mid-session can lose the very record it just earned.

Something is blocking the scripts the check needs

A check runs as a script, usually loaded from a domain belonging to the security provider rather than to the site you are visiting. Aggressive content blockers, script blockers, hardened privacy extensions and disabled third-party storage can all break that load. The check never completes, so it retries. From your side it looks like an infinite loop, or a challenge box that spins and never resolves.

Work through this in order:

1. 1Open the same page in a profile with no extensions at all. If the loop stops, an extension is your cause.
2. 2Re-enable extensions one at a time until it returns. Content blockers and privacy hardeners are the usual culprits.
3. 3Allow the challenge provider's domain in whatever blocked it, rather than switching the blocker off across the board.
4. 4Confirm JavaScript and third-party storage are not disabled for that site.
5. 5Check the system clock. A clock several minutes out will break the signed tokens a challenge depends on, and the failure looks nothing like a clock problem.

Symptom to cause

Match what you are seeing against the left column, and start with the fix in the right one.

What not to do

A few reflexes make this reliably worse.

• Do not randomise the profile's identity to shake off a check. A device that changes on every visit is a louder signal than whatever you were worried about, and it discards the stored evidence of every check you already passed.
• Do not clear cookies as a first response. Those cookies are the record of having passed. Clearing them guarantees the next visit starts from nothing.
• Do not stack a VPN on top of a proxy. You get two routes disagreeing about where you are, plus enough added latency to make ordinary timing look odd.
• Do not hammer reload. Repeated failed attempts from one address are precisely the behaviour a check is measuring.
• Do not move an account to a brand new route in the middle of a session. Finish the session, then change the route, then sign in again.

And one thing we will not help with. Solving these checks automatically sits outside what PowerOps does and outside what this blog will explain. Services that sell it exist. We do not integrate with them, we do not document them, and none of the product is built to get past a security check. Everything above is about removing the reasons a site has to ask in the first place. Answering the question on your behalf is a different business, and we are not in it.

If none of it works

Sometimes the check has nothing to do with you. A site under attack raises its threshold for everybody, and an entire country's traffic can sit behind a stricter rule for a day or two. Before you spend an afternoon on it, load the same page from an ordinary connection with no proxy and no profile involved. If the check is waiting there as well, the answer is to wait.

The rest of the time it comes down to a short list. A route with history behind it. A route that will not sit still. Values that disagree with each other. A browser that cannot keep what it earned. Fix those four and the checks go back to being an occasional annoyance rather than the shape of your working day.
