VPN On but Gemini and Claude Still Won't Open
Why Gemini or Claude will not open with a VPN on, and what to check in order: official country lists, exit address type, DNS, WebRTC, time zone and payment country.
ChatGPT Won't Open With a VPN On: Check Country, IP and Browser
A layered check: the official country list, the exit IP, the signals your browser sends and the account.
1. What a VPN changes and what it does not
A VPN changes one thing: the network address a service sees. It does not change the country of your account, tidy up the language and time zone of your browser, or turn a datacenter address into a home ISP address. So "the VPN is on and it still fails" is not yet a diagnosis. First find out what the service actually sees, then change something.
Decisions about access to an account are made by the platform itself. The IP is one input, not a switch that guarantees a result.
2. Step 1: compare your country with the official list
This is the cheapest check and takes a minute.
2. Step 1: compare your country with the official list
Open the official list
of supported countries and territories from OpenAI (the Supported countries and territories page in its documentation).
Find your country
The page opens with a sentence about accessing, or offering access to, the services outside the countries and territories listed below, so it is this list that sets the geography.
Do not swap the question
The list says where the service is offered; the exit address of a VPN does not change that. If your country is not on the list, the decision rests with OpenAI, not with network settings.
If you are in a supported country,
move on to the next steps: the cause is most likely the type of exit address or browser signals that do not agree.
3. Step 2: check the country and type of the exit IP
The country is not everything. The second important parameter is what type of network the address belongs to.
3. Step 2: check the country and type of the exit IP
| Item | What it shows | How to check |
|---|---|---|
| Exit IP country | The country the address is registered in | IP type check, country field |
| Organization and ASN | Whose network it is | IP type check, organization and ASN fields |
| Network type | hosting, isp, education, government or business | IP type check, type field |
| Stability | Whether the address changes between sessions | Repeat the test an hour later and on another day |
Note: field names and type values come from the IPinfo Core API documentation (read on 9 November 2026).
3. Step 2: check the country and type of the exit IP
Open the IP type check: it shows whether the address is classified as hosting or as an ISP address, and which country it is registered in. Compare the result with what your VPN client says. If the client claims one country and the test sees another, the problem is routing, not the service.
If a datacenter address behaves unreliably, it makes sense to move to an address that looks like an ordinary provider connection and keep it unchanged instead of switching exits every few minutes. The technical side is in the guide to setting up a proxy for ChatGPT.
4. Step 3: WebRTC, DNS, language and time zone
This is where you check that all the signals a service sees agree with each other.
4. Step 3: WebRTC, DNS, language and time zone
WebRTC
Under RFC 8828, WebRTC traffic should by default not be sent through proxy servers; when direct internet access is allowed, STUN checks do not go through the proxy and can reveal the client's public IP. The WebRTC leak test shows which addresses your browser exposes: if one belongs to your own provider or another country, the signals disagree.
DNS
Some queries may go through your local provider's DNS instead of the VPN. Run a DNS leak test from your client's settings or an online tool and compare the result with the country of the exit IP.
Language and time zone
If the IP is from one country, the interface is in the language of another and the system clock is in a third time zone, the signals contradict each other. Align the browser language and the system time zone with the country of the exit address.
4. Step 3: WebRTC, DNS, language and time zone
If the result is still unstable after Steps 2 and 3, read the breakdown of why the VPN still does not help and what to change next.
5. Step 4: one steady address for the whole session
Once the checks pass, the goal is simple: the address the service sees should come from a supported country, be of the isp type and stay the same between sessions. Frequent changes of exit create a gap between what the service saw at the start of a session and at the end.
For a ChatGPT subscription, Proxy302 has a GPT / Grok tier at 10 PTC for 30 days: one static ISP IP per AI subscription account, in the US, UK, France, Japan or Korea. The address stays fixed for the lease term. Choosing a country is covered in how to choose an ISP for an AI subscription, and the full scenario is on the ChatGPT subscription page.
How to do it with Proxy302
Proxy302's GPT / Grok tier gives one static ISP IP per AI subscription account for 30 days at 10 PTC, in the US, UK, France, Japan or Korea, and the address stays fixed for the lease term.
Run the checks above on the IP you receive and use the gateway proxy.proxy302.com with the protocol you generated: HTTP on port 2222 or SOCKS5 on port 3333.
How to do it with Proxy302: steps
Step 1
Open the product page that fits (static ISP, rotating residential or the ISP for AI subscriptions) and pick the region, traffic or lease term, and quantity. For per-IP products also choose HTTP or SOCKS5.
Step 2
After the proxy is generated, open My assets and copy HOST, PORT, USERNAME and PASSWORD.
Step 3
Open https://ipinfo.io/json through the proxy and check that the country and org fields (ASN and organization) are what you expected.
Step 4
Then compare network type and native or broadcast on the IP purity check page. Two tools disagreeing is normal; go by your actual use.
Prices and limits
Rotating residential starts at US$1.50 per GB on the Budget line and US$5 per GB on the Premium line; larger packages are cheaper per GB, and purchased traffic has no expiry. A static ISP IP is US$0.50 for one day or US$7.99 for 30 days, the same in every country, fixed for the lease. A datacenter IP is US$0.25 for one day or US$3.99 for 30 days. Stock changes daily, so go by the order page. The smallest purchase is 1 GB of traffic or one IP for one day. Changing IP does not lift a restriction or raise a limit; what happens to an account is up to the platform.

Prices are in PTC, paid from the wallet; 1 PTC = US$1. There is no free trial: the smallest purchase is 1 GB of rotating residential traffic or one IP for one day. Checked on 9 November 2026.
FAQ
Why did ChatGPT stop working through the VPN when it used to open?
The country or type of the exit address may have changed, or your browser's signals may no longer agree. Go through the steps in order: the country list first, then the IP type, then WebRTC, DNS, language and time zone.
Do I need a VPN if I already have a proxy?
They are different tools: a VPN routes the whole device's traffic, a proxy routes a specific app or browser. For ChatGPT what matters is not the connection method but the address the service sees: its country, type and stability. Two layers at once give more places for mismatches, so keep one.
How do I tell whether the problem is the address type rather than the country?
Open the IP type check: if the country fits but the address is classified as hosting, the type is the issue. A mismatch between the country in the test and the one in your client points to routing.
Can changing the address guarantee access?
No. An IP changes only the network address a service sees. The decision about an account is made by the platform and depends on the account's details and the service's rules.
What if none of the checks helped?
Write down what the tests showed (country, type, organization, WebRTC result) and contact the service's support with those details. That is quicker for finding the mismatch than changing settings at random.
