ChatGPT Not Working? How to Fix Common Errors (Network Error, Something Went Wrong and More)

ChatGPT not working? Whether you see “Something went wrong”, a network error, an endless “Thinking…” spinner or a blank screen, most problems fall into a few causes: an outage on OpenAI’s side, your browser or extensions, your network or VPN, or your account. This guide walks you through quick checks first, then explains the most common ChatGPT error messages and the fixes OpenAI itself recommends, so you can get back to work fast.

The fixes below are based on OpenAI’s own help-centre guidance on troubleshooting ChatGPT error messages, checked on 10 October 2026. Menus and error wording can change, so if a step does not match what you see, follow the latest instructions on OpenAI’s help centre.

Quick Fixes: Try These First

1. Check whether ChatGPT is down. Visit OpenAI’s status page (status.openai.com). If there is an incident, the only fix is to wait.
2. Refresh or start a new chat. Many errors are temporary. Very long conversations can also slow ChatGPT down.
3. Try a private or incognito window. This rules out extensions and saved site data in one step.
4. Turn off your VPN, proxy or secure DNS. OpenAI lists these as a common cause of connection errors.
5. Switch network or device. Try mobile data instead of Wi-Fi, or the app instead of the browser.
6. Sign out and back in. This refreshes your session.

If ChatGPT works in a private window, the problem is most likely an extension or saved data in your normal browser. If it fails everywhere, check the status page again or move on to the error-specific fixes below.

Is ChatGPT Down Right Now?

Before changing any settings, confirm whether the problem is on OpenAI’s side. The official status page shows current incidents for ChatGPT, the API and other services. If several people around you see the same error at the same time, it is likely an outage. During an outage, clearing your cache or reinstalling the app will not help.

If you rely on AI for work, it is worth having a backup assistant ready. Our comparisons of Perplexity vs ChatGPT and ChatGPT vs Gemini vs Claude cover the main alternatives, and Gemini’s free plan is described in our Gemini pricing guide.

Common ChatGPT Error Messages and How to Fix Them

“Something went wrong”

What it means: OpenAI describes this as a general error, usually a temporary server issue or a local setup problem.

How to fix it: refresh the page or start a new chat. If it keeps happening, clear your browser cache and cookies, disable extensions, turn off any VPN and try another browser.

“A network error occurred” or “An error occurred while connecting to the websocket”

What it means: your device cannot keep a stable connection to OpenAI’s servers.

How to fix it: turn off VPNs, proxies and web-protection or security filters, then try another browser, a private window, a different network or another device. Workplace and school networks can block some connections, so testing on a home or mobile connection helps narrow down the cause.

“There was an error generating a response”

What it means: ChatGPT could not produce an answer this time.

How to fix it: click Regenerate, because it may be a one-off. If it persists, restart your device, disable VPNs and proxies, turn off security filters and try another browser or network.

Stuck on “Thinking…”, “Generating…” or an endless spinner

What it means: the response is taking too long or the interface has frozen.

How to fix it: OpenAI suggests this order:

1. Wait 30 to 60 seconds.
2. Click “Stop generating”, then “Regenerate”.
3. Start a new chat and resend your prompt.
4. Hard-refresh the page or reload the desktop app.
5. Sign out and back in.
6. Test in a private window with extensions disabled.
7. Turn off VPNs, proxies and secure DNS.
8. Try another browser, network or device.
9. Check the status page.

“There was a problem preparing your chat”

What it means: an extension or URL blocker is interfering with how the page loads.

How to fix it: disable extensions that block scripts or change page content, especially ones you do not recognise, then try a private window or a different browser.

“We detect suspicious activity” or “Unusual activity detected”

What it means: your traffic looks automated or unusual to OpenAI’s systems.

How to fix it: switch off VPNs or proxies that may use flagged IP addresses, restart your browser or device and start a fresh private session. Make sure nobody else is using your account; if in doubt, change your password and secure the email address linked to it. If you do not use bots or automation and the message continues, contact OpenAI support.

Blank screen, frozen page or endless loading

What it means: the page is not rendering, with no error shown.

How to fix it: hard-refresh or force-reload the app, sign out and in, clear site data and cookies for ChatGPT, disable extensions and content blockers, and try a private window, a fresh browser profile or a different browser.

“Download failed” or “File not found”

What it means: a file ChatGPT created cannot be downloaded from its link.

How to fix it: generated files expire quickly, so ask ChatGPT to create the file again. Turn off VPNs or proxies, and make sure the file is under OpenAI’s stated 512 MB limit. If you use a custom GPT, OpenAI says Code Interpreter must be enabled and the GPT saved.

“Phone number required”

What it means: the Windows or macOS app is asking you to verify a phone number.

How to fix it: add a mobile number from a supported country or region and complete the verification.

ChatGPT Not Working on Your Phone

The same principles apply in the mobile app:

• Check for updates in the App Store or Google Play and install the latest version.
• Switch between Wi-Fi and mobile data to rule out your network.
• Turn off any VPN or private DNS setting on your phone.
• Force-close and reopen the app, then sign out and back in if needed.
• Try the website in your phone’s browser to see whether the problem is the app or your account.

Problems That Are Not Errors

Sometimes ChatGPT works but does not do what you expect:

• You have hit a usage limit. Free and paid plans have limits on some models and tools. Our ChatGPT pricing guide explains what each plan includes.
• A feature is not available on your plan or in your country. New features often roll out gradually.
• Answers seem wrong or outdated. This is a model limitation, not a fault. Ask ChatGPT to search the web, or check important facts yourself.
• Login problems. Make sure you use the same sign-in method you signed up with, such as Google, Microsoft, Apple or email.

If you are new to the tool, our beginner’s guide on what ChatGPT is and how to use it covers the basics.

When to Contact OpenAI Support

If nothing above works and the status page shows no incident, contact OpenAI through its help centre. OpenAI recommends recording a HAR file (a log of your browser’s network activity) while reproducing the problem, plus any console errors with timestamps, the model you were using and the conversation link. A HAR file can contain sensitive information such as session data, so share it only with official OpenAI support.

How to Prevent ChatGPT Problems

• Keep your browser and the ChatGPT app up to date.
• Limit browser extensions, especially script blockers, on the ChatGPT site.
• Start new chats for new topics instead of keeping one enormous conversation.
• Save important outputs, especially generated files, as soon as they appear.
• Keep a backup assistant for urgent work.

Browser-Specific Fixes

If ChatGPT only fails in one browser, the fix usually lies in that browser’s own settings. Menu names vary slightly between versions, but the steps below show where to look.

• Chrome: open chrome://extensions and switch off extensions one at a time, starting with ad blockers, script blockers and AI sidebars. To clear saved data for ChatGPT only, click the icon to the left of the address bar while on chatgpt.com, open site settings and delete its data.
• Safari: on a Mac, go to Safari > Settings > Privacy > Manage Website Data, search for “chatgpt” or “openai” and remove those entries. On iPhone and iPad, the equivalent option is under Settings > Safari > Advanced > Website Data.
• Firefox: strict Enhanced Tracking Protection can block parts of some sites. Click the shield icon in the address bar and turn protection off for chatgpt.com to test whether that is the cause.
• Edge: strict tracking prevention can have the same effect. Try the balanced setting, or add an exception for chatgpt.com, then reload.

ChatGPT Not Working at Work or School

Company and school networks often filter traffic. If ChatGPT works at home or on mobile data but not on the office or campus network, the network is the likely cause, not your device. Ask your IT team whether ChatGPT and OpenAI domains are allowed, and do not try to bypass the filter with a VPN, because that may break your organisation’s rules and can also trigger ChatGPT’s suspicious-activity checks.

On a managed laptop, security software and browser policies set by your employer can also block ChatGPT or some of its features, such as file uploads. In that case, only your IT team can change the setting.

Frequently Asked Questions

Why is ChatGPT not working today?

Either OpenAI has an outage, which you can check on its status page, or something on your side, such as a VPN, browser extension or network, is blocking the connection.

How do I fix “Something went wrong” in ChatGPT?

Refresh or start a new chat. If it continues, clear cache and cookies, disable extensions, turn off your VPN and try another browser.

Why does ChatGPT keep saying network error?

Your connection to OpenAI’s servers is unstable or being blocked. Turn off VPNs, proxies and security filters, and try another network or device.

Why is ChatGPT stuck on “Thinking”?

The response has stalled. Wait up to a minute, stop and regenerate, or start a new chat. Long conversations are more likely to slow down.

Does clearing the cache fix ChatGPT?

It often helps with blank screens and loading problems, but it will not fix an outage on OpenAI’s side.

Conclusion

When ChatGPT is not working, start by checking OpenAI’s status page, then work outwards from your side: refresh, try a private window, turn off VPNs and extensions, and switch network or device. Match the error message to the fixes above, and if nothing helps, contact OpenAI support with a HAR file.
