You open ChatGPT, type a prompt, and get a spinning cursor, a "Something went wrong" banner, or a human-verification page that loops forever. Then a colleague on the next desk uses it without a hiccup. That combination — broken for you, fine for them — is the most common way ChatGPT fails, and it almost never means the service is down.

Most of these failures come from the browser, not from OpenAI: an extension interfering with the security check, a privacy setting blocking the cookie that keeps you logged in, a cached service worker from three versions ago, or a data-saving mode on your phone that kills a streaming response halfway through. This guide goes through them by browser and by device, with the exact settings to change, and is clear about where a VPN helps and where it does nothing.

Why is ChatGPT not working today?

Spend one minute on triage before changing anything.

Check the status page first. status.openai.com lists active incidents for ChatGPT and the API separately. If there is an ongoing incident, stop — every fix below is wasted effort until it clears.

Then check whether it is you or the service. Open ChatGPT in a private/incognito window with extensions disabled. If it works there, the problem is in your normal browser profile — an extension, a cookie, or cached data — and the next two sections fix it. If it fails there too, move on to the network.

Then check a second network. Turn off Wi-Fi on your phone and load ChatGPT on mobile data. If it works, the network you were on is the variable, not your account.

The error text itself is a useful clue. A "Something went wrong" banner usually means a session or cookie problem. A network error partway through a long answer is the streaming connection dropping. An endless "Verify you are human" loop is nearly always a browser privacy setting or extension. And if you see a message saying the service is not available in your location, that is OpenAI's own list of supported countries, which matters mostly when you travel.

ChatGPT not working on Chrome

Chrome accounts for most reports, largely because it is where people install the most extensions.

  1. Test in Incognito. Ctrl+Shift+N (or Cmd+Shift+N). Extensions are off by default there. If ChatGPT works, an extension is the culprit — re-enable them one at a time. Ad blockers, privacy guards, script blockers and "AI assistant" extensions that inject themselves into the page are the usual offenders.
  2. Allow third-party cookies for the site. Strict cookie blocking breaks the security check and produces the infinite verification loop. Go to chrome://settings/cookies, scroll to the "Allowed to use third-party cookies" list, and add [*.]chatgpt.com.
  3. Clear the site's data only. Go to chrome://settings/content/all, search for chatgpt.com, and delete its data. This clears the stale service worker and cookies without logging you out of everything else you use.
  4. Update Chrome and restart it fully. chrome://settings/help updates it; then quit completely rather than just closing the window, because a background process keeps the old version alive.
  5. Turn off hardware acceleration in chrome://settings/system if the page renders but scrolls like a slideshow.
  6. Switch DNS to 1.1.1.1 or 8.8.8.8 if the page will not resolve at all.

ChatGPT not working on Safari

Safari's privacy features are good, and two of them collide with ChatGPT's security check.

  • Prevent Cross-Site Tracking. On iPhone and iPad this is under Settings → Apps → Safari; on Mac it is Safari → Settings → Privacy. Turn it off temporarily and reload. If the verification loop clears, you have found it — you can leave it off just for this site or accept the trade-off.
  • iCloud Private Relay. Under Settings → [your name] → iCloud → Private Relay. It routes Safari traffic through Apple's relay, which sometimes lands you on an address the security check does not like. It also cannot run at the same time as a VPN. Turn it off as a test.
  • Content blockers. Under Settings → Apps → Safari → Extensions on iOS. Same logic as Chrome extensions: disable, reload, re-enable one at a time.
  • Clear website data for one site. Settings → Apps → Safari → Advanced → Website Data, search chatgpt.com, swipe to delete. Far better than clearing all history.
  • If everything fails in Safari but works in Chrome, it is Safari-specific — use the app in the meantime and work through the list above.

ChatGPT not working on iPhone

The app has its own set of failure modes, distinct from the browser.

Low Data Mode is the big one. Under Settings → Cellular → Cellular Data Options, and separately per Wi-Fi network via the (i) button. ChatGPT streams answers token by token over a long-lived connection, which is exactly the kind of traffic Low Data Mode throttles — the symptom is answers that start and then stop dead.

Next, Background App Refresh under Settings → General; then confirm the app is current in the App Store, because older builds do get broken by server-side changes. If the app hangs on launch, offload it via Settings → General → iPhone Storage → ChatGPT → Offload App and reinstall — this clears its cache without deleting your account or chat history, which live on the server. If voice mode specifically fails, check microphone permission under Settings → ChatGPT. And if you have a VPN and iCloud Private Relay both enabled, disable one; they conflict.

ChatGPT not working on Android

The pattern is the same, with different menus.

Set the app to Unrestricted under its battery settings — aggressive battery optimization on Samsung, Xiaomi, OnePlus and similar devices suspends the app the moment you switch away, cutting a streaming answer in half. Turn off Data Saver in the system network settings. Clear the app cache via App info → Storage → Clear cache (not Clear data, which signs you out). If you use ChatGPT in Chrome on Android rather than the app, also update Android System WebView from the Play Store — an outdated WebView breaks embedded logins in ways that look like server errors.

ChatGPT not working properly: slow, cut-off or missing answers

Not every failure is a hard error. The "works, but badly" category has its own causes:

Symptom Likely cause Fix
Answer starts then stops Streaming connection dropped Disable Low Data Mode / Data Saver; retry on another network
"Something went wrong" on send Stale session cookie Clear site data for chatgpt.com, sign in again
Endless human-verification loop Extension or cookie blocking Incognito test; allow third-party cookies for the site
Chats missing from the sidebar Signed into a different account Check the account email in the bottom-left menu
Very slow replies at peak hours Server-side load Check the status page; try a lighter model
Uploads or file analysis fail File type, size, or a proxy stripping uploads Try a smaller file on a different network

One honest note on the last row: corporate proxies frequently interfere with file uploads while leaving text chat working, which makes the failure look random.

ChatGPT not working on a work, school or hotel network

Managed networks are their own category. Offices, campuses and hotels filter traffic by policy, and AI tools are often on the list — so ChatGPT fails there while working fine on your phone's mobile data. That is a decision made by whoever runs the network, and if it is your employer's device or your employer's network, respect their policy; a technical workaround is not the right move, and may breach your acceptable-use agreement.

Travel is a different matter. If you see a message that the service is not available in your location, that is OpenAI's own list of supported countries rather than anything your device is doing. Hotel and airport Wi-Fi also tends to be an open network shared with strangers, where encrypting your traffic is simply good practice regardless of ChatGPT.

How to choose a VPN for ChatGPT

Where a VPN genuinely helps: on public and hotel Wi-Fi, where it encrypts everything you type so the network's owner and everyone else on it see nothing; when you travel and want a stable, predictable route rather than whatever the local network gives you; and when your privacy matters — an AI chat contains some of the most personal text you will ever type, and your network provider has no business seeing where it goes.

What to look for:

  • Speed and stable throughput. Streaming answers and voice mode need a steady connection, not just a fast peak.
  • Servers in several countries with quick switching, so you can pick a nearby one wherever you are.
  • A modern protocol such as VLESS or WireGuard — low overhead, works well on mobile.
  • A real no-logs policy. The point of privacy is that nobody keeps a record, including your VPN.
  • Every device on one subscription — laptop, phone and tablet.

Orris VPN covers those: up to 1 Gbit/s, VLESS, unlimited traffic, no logs, servers in several countries, and Windows, macOS, Linux, iOS and Android from a single account — from about $1.7/month, with a free trial and payment by card or crypto.

What a VPN will not fix

Be clear about the limits, because this is where most disappointment comes from:

  • It cannot fix an OpenAI outage. If the status page is red, everyone is affected.
  • It cannot fix a browser extension. The verification loop caused by a privacy add-on follows you through any tunnel.
  • It will not give you a payment method. Billing is tied to your card and its issuing country.
  • It will not give you a phone number if a new account requires SMS verification.
  • It will not make a slow model fast. Response time at peak load is server-side.

FAQ

Why is ChatGPT not working today? Check status.openai.com first. If there is no incident, it is local: test in an incognito window with extensions off, then on a different network.

Why does ChatGPT keep saying "Something went wrong"? Usually a stale session. Clear site data for chatgpt.com only, reload and sign in again.

Why is ChatGPT stuck on "Verify you are human"? A privacy extension or strict cookie blocking is interfering with the security check. Allow third-party cookies for the site and test in incognito.

Why does ChatGPT not work on Safari but works on Chrome? Prevent Cross-Site Tracking, a content blocker, or iCloud Private Relay. Disable each in turn and reload.

Why do ChatGPT answers stop halfway on my phone? Low Data Mode on iPhone or Data Saver and battery optimization on Android cut the streaming connection. Set the app to unrestricted.

Is ChatGPT down or is it just me? Open it in a private window on mobile data. If it works there, it is your browser or your network, not the service.

Does a VPN help ChatGPT work better? It helps with privacy on shared networks and gives you a stable route when travelling. It does nothing about outages, extensions or billing.

Conclusion

The great majority of ChatGPT failures are browser failures wearing a server error's clothes. Check the status page, test in a clean incognito window, then work through the specific settings for your browser and device: third-party cookies and extensions in Chrome, Prevent Cross-Site Tracking and Private Relay in Safari, Low Data Mode on iPhone, battery optimization and Data Saver on Android. That sequence resolves nearly everything.

What is left is the network itself — a shared café connection, hotel Wi-Fi, an unpredictable route while travelling. That is the part a VPN is actually for: encrypted traffic and a predictable path on every device you own. If you want that set up on iOS in five minutes, see our VLESS guide for iPhone; if you would rather not attach a card to the subscription, we cover paying for a VPN with crypto; and if you are still weighing it up, start with what a VPN actually does.
