You connect to a proxy with an American or European IP, but ChatGPT stubbornly responds in Russian, shows regional restrictions, or Gemini suddenly requires confirmation from an "unavailable region." The problem is not with the IP — it's correct. The issue lies in six other signals that neural networks and the protective systems of Google/OpenAI read alongside the address, revealing your true geolocation completely.
Why One IP Address Is Not Enough
OpenAI and Google have long stopped relying solely on IP to determine a user's region. Both companies have powerful anti-fraud systems originally designed to combat spam, phishing, and circumvention of sanctions — and these same systems now catch attempts to mask geolocation in order to access ChatGPT Plus, Gemini Advanced, or regional features unavailable in your country.
The system works like this: the IP address is just one parameter among dozens. The browser sends a batch of technical data with each request: the operating system's timezone, interface language, font list, screen resolution, WebGL rendering parameters, and TLS connection headers. If the IP says "USA," but the other 10-15 parameters say "Russia," the system concludes: the user is masking their identity, and applies restrictions — from lowering limits to completely blocking the account.
This is particularly critical for arbitrageurs and SMM specialists who create and warm up accounts en masse through anti-detect browsers like Dolphin Anty, AdsPower, or Multilogin — discrepancies in geosignals can instantly lead to a ban on the profile or the associated service account.
Signal 1: Real IP Leak via WebRTC
WebRTC is a protocol for video calls and voice communication in the browser, which is used, among other things, in the voice mode of ChatGPT. The problem is that WebRTC can directly query the operating system for a list of all network interfaces, including the real external IP, bypassing the proxy settings in the browser.
In practice, this looks like this: you access ChatGPT through a proxy with an IP from Germany, but as soon as you open a voice chat or any function tied to WebRTC, the service reads your real Russian or Ukrainian IP through a STUN server via a JavaScript request. This request does not pass through the proxy tunnel at all because it operates at the network stack level, not HTTP.
How to Check: open the website browserleaks.com/webrtc in the same browser profile where you work with the AI service. If the "Local IP Address" or "Public IP Address" block shows an address different from what the proxy provides, the leak is confirmed.
Solution: in anti-detect browsers (Dolphin Anty, AdsPower, GoLogin), there is a separate WebRTC setting — choose the "Replace" or "Disable" mode so that the browser either replaces the IP in WebRTC requests with the proxy address or completely blocks the protocol. In regular Chrome without anti-detect, you need to install an extension like WebRTC Leak Shield.
Signal 2: System Timezone
Each browser sends a timezone parameter to the server with each request via the JavaScript function Intl.DateTimeFormat().resolvedOptions().timeZone. This parameter is taken directly from the operating system settings, not from the IP address — and the proxy does not change it.
Imagine a situation: the proxy shows an IP from New York (timezone UTC-5), but your computer's clock is set to Moscow time (UTC+3). For bot detection systems, this is an instant red flag — real users from New York do not live by Moscow time. Gemini and ChatGPT use this parameter as part of the overall session "fingerprint."
Solution: the timezone must match the geolocation of the proxy with regional accuracy, not just country accuracy. In Dolphin Anty and AdsPower, the timezone is automatically pulled when entering the proxy IP — do not disable this function and do not set it manually "by eye."
Signal 3: Browser Language and Accept-Language Header
Each HTTP request from the browser contains the Accept-Language header, which informs the server of the preferred interface language. If you have a Russian-language Windows with the browser language set to "ru-RU," this header is sent to the ChatGPT server along with the request — regardless of what the IP address says is "US."
This signal is particularly indicative for systems like Gemini, which actively adjusts responses based on the user's language. If the model sees Accept-Language: ru but the IP is American — it either ignores the IP geolocation and still applies Russian-language restrictions, or it flags the discrepancy for Google's anti-fraud system.
Solution: in the settings of the anti-detect browser profile, change the system language and the browser language list to match the language of the proxy country. For the USA, this is en-US; for Germany, it is de-DE with a fallback to en-US. Don’t forget about regional settings for date and currency formats — some advanced checks look at these as well.
Signal 4: TLS/JA3 Fingerprint and Connection Type
This is the most technical and underrated signal. When establishing an HTTPS connection, the browser and server exchange encryption parameters — a set of supported algorithms, the order of TLS extensions, and other handshake details. This combination is unique for each "browser + operating system + network hardware" pairing and is called JA3/JA4 fingerprint.
The problem is that cheap datacenter proxies often have a characteristic network profile — providers like AWS, DigitalOcean, and OVH use hardware that forms a recognizable TLS fingerprint, different from a regular home internet connection through a mobile or cable network provider. Cloudflare's antispam systems, which protect the infrastructure of OpenAI, have been collecting databases of such fingerprints for years and flag traffic from datacenter ranges as suspicious even before analyzing the content of the request.
Solution: for working with AI services where convincing imitation of a regular user is important, it is advisable to use residential proxies — their IPs belong to real home providers, which means that the network profile of the connection looks organic, without datacenter flags.
Signal 5: DNS Leaks
Even if HTTP traffic goes through a proxy, DNS requests (the conversion of a domain name to an IP) sometimes continue to go directly through your internet provider's system resolver, bypassing the proxy tunnel. This happens due to incorrect proxy settings at the system level or the peculiarities of some VPN clients that confuse with proxies.
For the average user, a DNS leak is unnoticed, but for the server infrastructure of Google and Cloudflare, it is another parameter for verification: the DNS request came from one geographical region of the provider's resolver, while the HTTP request came from an IP of a completely different country. The discrepancy is logged and contributes to the overall scoring of session suspicion.
How to Check: visit dnsleaktest.com in your working browser profile and run the extended test. If the list of resolvers shows a provider from your real country, not from the proxy country — there is a leak.
Solution: use SOCKS5 proxies with forced routing of DNS requests through the proxy server itself (the option is usually called "Remote DNS" or "DNS through proxy"), rather than SOCKS4/HTTP proxies that do not fully support this capability.
Signal 6: Canvas, WebGL, and Hardware Parameters
Canvas fingerprinting is a technique where a website forces the browser to render an invisible graphic element and reads the smallest differences in rendering caused by the features of the graphics card, drivers, and fonts installed in the system. WebGL fingerprint works similarly, but analyzes 3D rendering parameters.
This does not directly relate to geolocation, but indirectly reveals a lot: the font set is typical for a specific locale of the operating system (Cyrillic fonts of Windows with Russian localization differ from the fonts of the American version of the same OS), and the model of the graphics card, combined with other parameters, can indicate the region where the hardware was sold.
Google and OpenAI use these parameters not so much for direct country determination but for linking several of your "different" accounts into a single cluster — if ten formally independent accounts have identical Canvas fingerprints, this is a clear sign of multi-accounting, and the entire chain gets banned simultaneously (chain-ban).
Solution: use anti-detect browsers with Canvas and WebGL randomization features for each profile — this feature is available in Dolphin Anty, AdsPower, Multilogin, Incogniton, and Octo Browser. Do not try to get by with regular Chrome with just a proxy switch for creating multiple accounts — the fingerprint will remain identical across all profiles.
Checklist: How to Close All 6 Signals
Before opening ChatGPT or Gemini through a new profile with a proxy, go through the list:
| Signal | How to Check | What to Set Up |
|---|---|---|
| WebRTC | browserleaks.com/webrtc | Replace/Disable mode in anti-detect |
| Timezone | Compare system time with IP region | Auto-pull timezone by proxy IP |
| Accept-Language | whatismybrowser.com | System language = proxy country language |
| TLS/JA3 | ja3er.com | Residential proxies instead of datacenter |
| DNS | dnsleaktest.com | SOCKS5 with remote DNS |
| Canvas/WebGL | browserleaks.com/canvas | Randomization in anti-detect browser |
What Type of Proxy to Choose for Working with AI Services
The technical settings of the browser solve only part of the problem — the foundation is still set by the proxy itself. Three main types behave differently in the context of the anti-fraud systems of ChatGPT and Gemini:
| Proxy Type | Risk of Flagging by Anti-Fraud | When to Use |
|---|---|---|
| Datacenter | High — noticeable TLS profile | One-time checks, test requests, not for long sessions |
| Residential | Low — IPs from real home providers | Long-term work with accounts, warming up, multi-accounting |
| Mobile | Minimal — shared NAT pool of operators | High-importance tasks where session stability is critical |
For most scenarios — ChatGPT Plus accounts from the required country, working with Gemini Advanced, testing regional features — the optimal balance of price and reliability remains residential proxies: they provide stable binding to a specific city and provider, which is critical for matching timezone, language, and network profile simultaneously.
Conclusion
A proxy changes only one parameter out of seven that ChatGPT and Gemini analyze to determine your real geolocation. WebRTC, timezone, browser language, TLS fingerprint, DNS resolver, and Canvas/WebGL fingerprint form a complete picture, and a discrepancy in even one of them is enough to trigger the anti-fraud system. The solution is a comprehensive approach: an anti-detect browser with a properly configured profile plus a proxy whose network profile does not stand out from regular users.
If you work with AI services on a regular basis — managing multiple accounts, testing regional features, or setting up automation through Dolphin Anty, AdsPower, or GoLogin — we recommend starting with residential proxies: they naturally close most technical signals of geolocation leakage without the need to manually adjust each browser parameter.
