Why a High Proxy Score Doesn’t Clear Your Browser
The Pixelscan proxy checker grades a proxy address, not the browser you route through it. It returns a 0-100 rating for speed, stability and reliability, plus a fraud score, an ASN lookup and a location, and it accepts a single IP:PORT or a .txt list. A strong score means the address behaves like an ordinary connection. It says nothing about your timezone, language list or WebRTC candidates, which are measured separately in the browser scan.
📌 TL;DR Executive Summary
- Core Takeaway: Pixelscan compares IP-side signals (geolocation, User Type, IP time) against browser-side signals (timezone, languages, WebRTC candidates, canvas and WebGL hashes) and reports where the two sets disagree. “Inconsistent fingerprint” means a mismatch exists, not that your hashes are unusual.
- Key Risk/Challenge: An HTTP or SOCKS proxy cannot carry the UDP packets WebRTC uses, so candidate gathering can leave through your real network interface — and an address whose ASN is registered as hosting gets a datacenter User Type on sight.
- Recommended Solution: Verify the address type and ASN first, align timezone, locale and language with the exit IP, restrict WebRTC to proxy-only paths, and keep one profile per account so each identity stays internally coherent.
Two Different Tools Share One Name
Search for Pixelscan and you land on a free multichecker that runs in the tab you already have open: fingerprint analysis, IP and proxy checks, DNS leak detection, bot detection and blacklist scanning, with no signup and no install. Pixelscan states on its own homepage that more than five million scans have run through it and reports a 99.95% accuracy rate — vendor figures, not independently verified.
That page is not the Pixelscan Proxy Checker. The proxy checker is a separate desktop application with Chrome and Firefox extensions: it takes one IP:PORT or a .txt list and grades each address on speed, stability, reliability, fraud risk and location. New accounts get 100 checks without a card. For volume, Pixelscan’s bulk checker auto-detects ip:port, tab, space or CSV input, handles batches from 10 to 100,000+ addresses, queues long runs in the background and exports graded CSV or JSON. Pixelscan sells it in 2,500 and 10,000-check tiers.
What neither tool does
The proxy checker never touches a browser profile. A 100/100 address is still only an address; it cannot tell you whether your timezone, language list, WebRTC candidates and proxy country agree. Those mismatches are what most people are chasing when the browser scan goes red, and the cause is usually a profile setting rather than the proxy — how Pixelscan detects mismatches walks through that comparison.
Both tools are diagnostics. Neither guarantees that a particular website will treat your session as ordinary, and treating a clean report as a certificate is where people go wrong.
How Pixelscan Reaches Its Verdict
The scanner collects two sets of values and compares them. Nothing exotic happens in between.
Two signal sets, compared for disagreement
On the IP side it reads the geolocation attached to the exit address, the User Type derived from ASN and range data, and a time value taken from the IP. On the browser side it reads the timezone your JavaScript reports, your language list, WebRTC ICE candidates, and rendering hashes from canvas, WebGL, AudioContext and fonts.
“Your Browser Fingerprint is inconsistent” is a statement about those two columns not agreeing somewhere. It does not mean your hashes are rare or shared. A profile can have perfectly ordinary hashes and still fail because its exit IP sits in Frankfurt while its clock says Los Angeles.
Why canvas, WebGL and audio count as hardware evidence
Canvas and WebGL output depends on the GPU and its drivers, so the same drawing instruction produces slightly different pixel values on different machines; AudioContext does something similar with audio processing paths. Pixelscan reads those outputs alongside user agent, platform, fonts, screen resolution, language, timezone and hardware concurrency, then asks whether they look like one coherent device. A machine claiming to be a MacBook with an Intel GPU string and Windows font metrics fails that test before any network check runs.
The WebRTC channel an HTTP proxy cannot carry
WebRTC asks a STUN server over UDP. An HTTP proxy cannot carry UDP, and browsers do not route that traffic through SOCKS either, so the packet can leave through your real interface and come back carrying your public address. Any page can collect those ICE candidates without a permission prompt. In a Chrome 154 test without the policy switch, candidate gathering returned one host and one srflx candidate; with --webrtc-ip-handling-policy=disable_non_proxied_udp it returned nothing.
Chromium’s WebRTC IP handling policy has four values, and only disable_non_proxied_udp closes the path by sending nothing over UDP unless it goes through the proxy. The default, default_public_interface_only, still leaks behind a proxy. Firefox exposes the equivalent control as media.peerconnection.ice.proxy_only in about:config, and Brave puts the four policy values directly in settings.
What the Verdict Means for Real Work
Risk engines on signup, checkout, advertising and moderation endpoints look for internal contradiction. An account that registers from a German address but logs in with an en-GB language list, a Los Angeles clock and a WebRTC candidate pointing at a home ISP is not obviously fraudulent — it is inconsistent, and inconsistency is what pushes a session into a manual review queue.
This bites hardest when you run several identities from one machine: agencies managing client accounts, sellers with more than one storefront, social media managers, and QA or support teams testing as different users and regions. That is also why one profile per account is the structural fix. Twenty profiles on one laptop sharing a clock and a canvas hash start compounding mismatches; a single profile on a home connection rarely trips anything.
One limit applies regardless of how tidy your setup is: if a platform restricts how many accounts you may hold, that rule stands. Amazon requires approval for an additional seller account, and agencies working on Meta properties use Business Manager roles rather than extra logins. A restricted or suspended account is fixed through the platform’s appeal or verification process, not through a settings change.
Reading the Report Line by Line
Not every line carries the same weight. Some describe the network, some describe the browser, and one or two are informational only.
| Report line | What it compares | What a flag usually means | First fix to try |
|---|---|---|---|
| Proxy tile | Whether the request arrived through an address the scanner recognises as proxy infrastructure | “No proxy detected” is normal for a carrier mobile IP behind CGNAT; a datacenter User Type on something sold as mobile means the address resolves to hosting or a stale record | Check the ASN independently before touching browser settings |
| User Type | IP-side classification built from ASN and range data | A hosting range, or an overused public VPN exit recognised on sight | Move to a residential address or an authorised connection |
| Timezone | IP-side time against the browser timezone | Two clocks in two regions | Set the profile timezone to the exit IP |
| Languages | navigator.languages against the Accept-Language header, then both against the proxy country | A US exit with an en-GB or ru-RU list, or a header that contradicts the JavaScript list | Align the list first, then the header |
| WebRTC | ICE candidates gathered over UDP via STUN | Your real public address appears next to the proxy address | Set the policy so UDP only leaves through the proxy |
| DNS | Which resolvers answered and where they sit | Resolvers in a different country from the claimed location | Send DNS through the proxy or a resolver near the exit |
| Bot check | Input patterns recorded during the scan itself | Informational — an automated run reads differently from a hand-driven one | Re-run by hand as a control |
| Canvas, WebGL, audio, fonts | Rendering output, which depends on GPU and drivers | Identical values across profiles that should be separate devices | Keep one profile per account |
A Practical Fix Checklist
Work top to bottom; each step is verifiable on its own, so you can tell which one changed the verdict. The same steps apply to any checker that compares IP-side values with browser-side ones — WhoerIP, Infatica, Proxyway and similar tools read the same clusters.
- Verify the IP first. Look up the ASN, address type and geolocation in a neutral lookup before you touch the browser. If the range is hosting, no amount of profile tuning changes the User Type line, and the difference between residential and datacenter proxies explains why that matters more than any other setting.
- Match the timezone to the exit IP. Not to your own location, and not to a neighbouring city “close enough”. The IP-side time is read from the address, so a one-hour offset still registers as a mismatch in some regions.
- Fix the language list before the header. The check reads
navigator.languagesfrom JavaScript and compares it to the Accept-Language header, then tests both against the proxy country. Most browsers derive the header from the list, so correcting the list usually corrects the header too. - Handle WebRTC at the policy level. Turning WebRTC off entirely works, but it also removes a capability real browsers use for calls and conferencing. Sending nothing over UDP unless it goes through the proxy keeps the feature and closes the leak.
- Check DNS separately. A leak-free proxy with resolvers in another country still produces a mismatch. Point DNS at the proxy or at a resolver in the exit region.
- Set locale, geolocation and WebRTC in one pass. All three derive from the same decision — which region this profile belongs to. Doing them together avoids the half-migrated state where two values say Berlin and one still says Lisbon.
- Re-run and compare, don’t just read. Keep the previous result. A verdict that moved from inconsistent to consistent tells you the fix worked; one that did not move tells you the mismatch lives somewhere else.
Common Mistakes That Keep the Report Red
- Assuming the proxy checker app tests your browser. It does not. A perfect score there sitting next to a red browser scan is the expected outcome when the problem is profile-level.
- Reading “No proxy detected” as a failure. Carrier mobile IPs behind CGNAT commonly produce exactly that, because the address is shared carrier infrastructure rather than a recognised commercial proxy range. It is a description, not an error.
- Treating “datacenter” as a bug. If the ASN says hosting, the label is correct. Re-testing the address will not change what the range is registered as.
- Editing hash-level settings instead of network-level ones. Canvas and WebGL values that agree across profiles usually mean two profiles share a machine, not that a fingerprint is wrong. The cluster that gets flagged is timezone, language and WebRTC, and it lives at the network layer.
- Rewriting every signal you can find. A profile whose values were changed in bulk can look less coherent than a default one, because the parts stop fitting together. Consistency beats volume.
- Rescanning without a control. Run the scan once on an untouched profile in the same browser. That baseline is the only comparison that means anything on your machine and network.
How Send.win Helps With Pixelscan Proxy Checker
Send.win is a browser profile manager for professionals and teams: every account gets its own isolated browser profile.
- Isolated profiles – separate cookies, storage and sessions per profile
- Fingerprint protection – each profile keeps its own consistent browser fingerprint, so profiles never share one browser identity
- Desktop app + cloud browser – native app for Windows, macOS and Linux, or run profiles in the cloud with no install
- Residential proxies included – on Pro and Team, with timezone and locale matched to the proxy
- Team sharing – share a signed-in profile with a teammate without sharing the password
Try the free cloud demo — no install — or download the desktop app. Paid plans start at $19/month, and your first card purchase is covered by a 7-day money-back guarantee (see pricing).
Where Send.win Fits
The mismatches this scanner reports are mostly consequences of how a browser is configured, not of the proxy itself. Send.win is a browser profile manager built around that idea. Each isolated profile carries its own cookies, storage, sessions, fingerprint settings and proxy, and timezone, locale, WebRTC and geolocation follow the proxy’s exit IP automatically — the exact cluster of values the scan compares.
It runs two ways. Sendwin Browser is a native desktop app for Windows 10/11, macOS 12+ and Linux, built on Chromium and installed locally. The cloud browser runs profiles on Send.win’s server in Helsinki, Finland, reachable from any device with nothing to install. The free cloud demo at send.win/demo-browser gives you a three-minute preview without a signup, and a free account gets ten minutes a day.
For teams, sharing a profile with a paid teammate opens it already signed in, so no password changes hands, and cloud sync keeps logins available across devices. If you are weighing that structure against a plain browser with a proxy attached, what a proxy browser is covers the trade-offs directly.
One thing Send.win is not: a scripting platform. There is no API, SDK, headless mode or support for browser automation frameworks such as Selenium, Puppeteer or Playwright on any plan. Profiles are opened and used by a person, in a window — you set the profile up once, and every session you run from it starts from the same configuration.
🏆 Send.win Verdict
Pixelscan tells you where your IP and your browser disagree. It cannot stop them disagreeing, because the values it reads — timezone, locale, WebRTC candidates, per-profile storage — are set by the browser you run. Send.win sets them per profile from the proxy’s exit IP, so the two signal sets line up by default rather than after a debugging session. Pro includes 150 saved profiles, 20 residential proxies and 5 GB/month of bandwidth; Team raises that to 500 profiles, 20 GB and 16 seats.
See Send.win plans — Pro from $19/mo or $83.88/yr, with a 7-day money-back guarantee on your first card purchase, or try the free cloud demo first if you would rather look before you buy.
Frequently Asked Questions
Why does Pixelscan say I am using a proxy?
Because your request arrived from a range Pixelscan recognises as commercial proxy or hosting infrastructure, or a public VPN range it has on file. It reads ASNs and ranges, so well-known datacenter blocks and heavily used VPN exits are flagged immediately. The label describes the address, not your intent.
What does “your browser fingerprint is inconsistent” mean?
It means the IP-side set and the browser-side set disagree somewhere — a Frankfurt exit with a Los Angeles clock, or a US address with an en-GB language list. It does not mean your hashes are unusual or shared. The fix is to align the values, not to change the hashes.
How do I fix a WebRTC leak it detected?
Set the browser’s WebRTC IP handling policy so UDP traffic only leaves through the proxy. In Chromium that means disable_non_proxied_udp, since the default value still leaks behind a proxy. In Firefox set media.peerconnection.ice.proxy_only to true in about:config, and Brave exposes the same four policy values in settings.
Does Pixelscan check my browser or just my IP?
The free scanner checks both in one pass, and its verdict comes from comparing them. The separate Pixelscan Proxy Checker app checks only the address: speed, stability, reliability, fraud score and location. That is why a high proxy score and a red browser verdict can both be correct at the same time.
What is the difference between Pixelscan and the Pixelscan Proxy Checker app?
The browser scanner is a free multichecker you run in a tab with no signup. The Proxy Checker is a desktop app with Chrome and Firefox extensions that takes an IP:PORT or a .txt list and grades each address, with 100 free checks for new users. The bulk version handles 10 to 100,000+ addresses per batch and exports CSV or JSON.
What does User Type “datacenter” mean, and is it a problem?
It means the ASN the address belongs to is registered as hosting rather than as a consumer or mobile network. If you bought the address as a residential or mobile proxy, the label points at a stale database record or a reseller routing you through hosting. Check the ASN before you change anything in the browser.
How many proxies can Pixelscan check at once?
The bulk checker accepts 10 to 100,000+ addresses in a single batch and queues long runs in the background. It auto-detects the input format, so ip:port lists, tab-separated text, CSV and links copied from webpages all work without reformatting. The Firefox extension distributed for NodeMaven users is capped at 50 proxies per run and HTTP only.
Does a VPN fix a WebRTC leak that a proxy does not?
It changes the leak rather than closing it. A VPN moves the UDP packet along with the rest of your traffic, so candidate gathering returns the VPN address instead of your real one. That removes the proxy-versus-real-IP mismatch but introduces a different network path, which can create new timezone and geolocation disagreements.
