Why Is ChatGPT Not Working? 10 Fixes, Fastest First (2026)

Why is ChatGPT not working? In almost every case it is one of three things: an OpenAI outage, a broken browser session, or a usage limit you have hit. Check status.openai.com first: if OpenAI has an open incident, no local fix will help and waiting is the only option. If status is green, the cause is almost always browser-side. Clearing cache and cookies resolves most local failures; after that, disable extensions one at a time, try a private window, and test a second browser. The ten fixes below run from fastest to most involved and cover blank screens, error messages, responses that stall mid-answer, and logins that will not complete.

Few things are more frustrating than opening ChatGPT and getting a blank screen, an endless loading spinner, or a cryptic error message. Whether you rely on ChatGPT for work, coding, writing, or research, downtime kills productivity.

The good news: most ChatGPT issues have simple fixes. This guide covers the 10 most common problems and their solutions, ordered from quickest to most involved. We will also address a common concern, whether browser extensions cause conflicts, and explain why AI Toolbox is designed to avoid these issues entirely.

Why ChatGPT Is Not Working: Start Here

If ChatGPT is not working or appears down, work through these five checks in order: confirm an outage at status.openai.com, clear your browser cache and cookies, test in incognito mode, disable extensions one at a time, then switch browsers. Most failures are either server-side (wait it out) or browser-side (a cache clear fixes the majority of them).

To tell a real outage from a local problem fast: if status.openai.com shows an active incident, it is OpenAI's side and you simply wait. If the status page is green but ChatGPT still fails for you, the cause is on your device, your browser, or your network, and the fixes below resolve it.

Match the Symptom to the Fix

What you see on screen tells you which layer is failing: a blank page points at the browser, a stalled answer points at the network, and an error code usually points at OpenAI.

If you would rather skip straight to the relevant fix, find your symptom in the table below and start there instead of working through all ten in order.

Fix 1: Check if ChatGPT Is Down (Server-Side Issues)

Before troubleshooting anything on your end, check OpenAI's status page. If ChatGPT's servers are down, no amount of browser fixes will help.

OpenAI maintains a public status page at status.openai.com. Bookmark it. When ChatGPT stops working, this should be the very first place you check.

Downdetector is a useful second opinion, since crowd-sourced reports often spike a few minutes before an incident is officially posted.

If the status page shows degraded performance or an active incident, the only fix is to wait. OpenAI's engineering team typically resolves outages within 30 minutes to a few hours. During high-traffic periods (weekday mornings in US time zones), slowdowns are more common.

Fix 2: Clear Your Browser Cache and Cookies

A corrupted cache is the single most common browser-side cause of ChatGPT issues. Clearing it fixes blank screens, infinite loading, and login loops in the large majority of local failures.

Your browser stores cached versions of web pages, scripts, and cookies. When ChatGPT updates its frontend (which happens frequently), stale cached files can cause conflicts. Here is how to clear them:

Chrome:

1. Press Ctrl+Shift+Delete (Windows) or Cmd+Shift+Delete (Mac).
2. Set the time range to "All time."
3. Check "Cookies and other site data" and "Cached images and files."
4. Click "Delete data."
5. Reload ChatGPT.

Firefox:

1. Press Ctrl+Shift+Delete (Windows) or Cmd+Shift+Delete (Mac).
2. Select "Everything" for the time range.
3. Check "Cookies" and "Cache."
4. Click "Clear Now."

Edge:

1. Press Ctrl+Shift+Delete.
2. Select "All time."
3. Check "Cookies" and "Cached images and files."
4. Click "Clear now."

Note: clearing cookies will log you out of all websites. If you only want to clear data for ChatGPT, go to your browser settings, find "Site settings" or "Cookies," search for "chatgpt.com" and delete only those entries.

Clearing site data never deletes your ChatGPT conversations, because those live on OpenAI's servers rather than in your browser. If you would rather not depend on that, keep your own copy: our guides to exporting ChatGPT conversations and to automatic ChatGPT backups cover both the manual and the scheduled route.

Fix 3: Try Incognito / Private Browsing Mode

Incognito mode runs a clean browser session with no cache, no extensions, and no stored cookies. If ChatGPT works there, the problem is in your regular browser profile.

Open an incognito window (Ctrl+Shift+N in Chrome, Ctrl+Shift+P in Firefox) and navigate to chatgpt.com. Log in and try using ChatGPT.

If it works in incognito but not in your regular browser, the issue is caused by one of these:

• Cached data (Fix 2 above)
• A browser extension conflict (Fix 4 below)
• A corrupted browser profile (rare but possible, see Fix 9 below)

Fix 4: Disable Browser Extensions (Find the Conflict)

Browser extensions that modify web pages, including ad blockers, privacy tools, and poorly coded ChatGPT extensions, are a leading cause of ChatGPT breaking.

Some extensions inject JavaScript or CSS into every page you visit, including ChatGPT. This can break the interface, prevent messages from sending, or cause blank screens. Common culprits include:

• Ad blockers (uBlock Origin, AdBlock Plus), which may block ChatGPT's API requests.
• Privacy extensions (Privacy Badger, Ghostery), which may block required cookies or scripts.
• Other ChatGPT extensions, where aggressive DOM rewriting causes conflicts.

To find the culprit, disable all extensions, confirm ChatGPT works, then re-enable them one by one until the issue returns. The last extension you enabled is the problem.

Note on AI Toolbox: AI Toolbox is built specifically to avoid these conflicts. It runs as a lightweight overlay that does not rewrite ChatGPT's core DOM elements or interfere with API requests. With 40,000+ active users and a 4.6/5 Chrome Web Store rating, it is one of the most reliable ChatGPT extensions available. If another extension turns out to be the conflict, our quick start guide walks through setting AI Toolbox up in a couple of minutes.

Fix 5: Switch to a Different Browser

If ChatGPT works in one browser but not another, the issue is browser-specific. Try Chrome, Firefox, Edge, or Brave to isolate the problem.

ChatGPT is optimized for modern Chromium-based browsers (Chrome, Edge, Brave) and Firefox. If you are experiencing issues:

1. Try a different browser entirely.
2. If it works, the issue is likely in your original browser's cache, extensions, or settings.
3. Make sure your browser is updated to the latest version, because ChatGPT uses modern web features that older browser versions may not support.

Safari on macOS generally works but has occasionally shown compatibility issues with ChatGPT's real-time streaming. If you use Safari and experience problems, switching to Chrome or Firefox usually resolves them. Note that AI Toolbox itself runs on Chromium browsers only, so Chrome, Edge, Brave, Opera, or Arc are the ones to test in if you want the extension available while you troubleshoot.

Fix 6: Check Your Internet Connection

ChatGPT requires a stable internet connection with low latency. VPNs, corporate firewalls, and unstable Wi-Fi are common network-level culprits.

ChatGPT streams responses in real-time, which requires a persistent connection. If your connection drops or has high latency, you may see:

• Responses stopping mid-sentence
• "Network error" messages
• Messages failing to send
• The chat interface loading but not responding

Quick network checks:

• Run a speed test at speedtest.net. You need at least 5 Mbps for smooth ChatGPT use.
• Disable your VPN temporarily. Some VPNs route traffic through regions where OpenAI's servers have higher latency, or they may be blocked entirely.
• Switch networks: Try mobile data instead of Wi-Fi, or vice versa.
• Check corporate firewalls: Some company networks block access to chatgpt.com or its API endpoints.

Fix 7: Rate Limits and the Caps That Still Exist in 2026

Since August 6, 2026, text chat is unlimited on every ChatGPT plan including Free, so a "Too many requests" message is rate limiting rather than a message quota.

This is the fix most guides still get wrong. The old numbers, roughly 10 messages per 5 hours on Free and roughly 160 per 3 hours on Plus, no longer apply to text. If you are rationing messages, you are optimizing against a constraint that was removed. Our full breakdown of ChatGPT limits covers the change in detail.

What that leaves is two different things people confuse with each other:

• Rate limiting (429 errors). Send prompts faster than OpenAI's per-account throttle allows, usually by hammering regenerate or running several tabs at once, and you get temporarily blocked even with no quota in force. Slow down and it clears on its own.
• Feature caps. Image generation, file uploads, and voice each keep their own separate allowances, and Deep Research and Agent mode remain paid features. These are the caps that still bite.

Free and Go accounts cannot reach GPT-5.6 Sol in a regular chat at any usage level. That is a hard gate rather than a rate limit, so no amount of waiting will unlock it. If you are not sure which model you are on or what the effort levels do, see our guide to the current ChatGPT models and the companion piece on reasoning modes.

Fix 8: Log Out and Log Back In

Authentication token expiration causes "session expired" errors and unexpected logouts, and a clean re-login refreshes your session.

ChatGPT uses authentication tokens that expire periodically. If your session becomes stale, you may experience:

• Being logged out unexpectedly
• "Something went wrong" errors
• The sidebar loading but the chat area remaining blank

To fix: log out completely from ChatGPT (click your profile icon, then "Log out"), close the tab, reopen it, and log back in. If you use multiple OpenAI accounts, make sure you are logging into the correct one. When the login itself is what fails, our ChatGPT login guide covers the SSO, verification, and email-mismatch cases in order. If the account is blocked rather than the session, the suspended account recovery guide is the right starting point.

Fix 9: Update Your Browser or Try a Fresh Profile

An outdated browser or a corrupted user profile can cause persistent issues that cache clearing alone does not fix.

Check your browser version:

• Chrome: Go to chrome://settings/help, which updates automatically if needed.
• Firefox: Go to about:preferences and check for updates.
• Edge: Go to edge://settings/help.

If updating does not help, try creating a new browser profile. In Chrome, click your profile icon in the top-right corner and select "Add." A fresh profile has no extensions, no cache, and no corrupted data. If ChatGPT works perfectly in the new profile, the issue is in your old profile and migrating is worth the effort. Anything you had saved in AI Toolbox follows you across, because folders, prompts, and tags sync to your account rather than living in one browser profile.

Fix 10: Disable Hardware Acceleration

Hardware acceleration offloads rendering to your GPU, but on some systems it causes rendering glitches, blank screens, and frozen pages in web apps like ChatGPT.

This is a less common fix but worth trying if nothing else works:

Chrome:

1. Go to chrome://settings/system.
2. Toggle off "Use hardware acceleration when available."
3. Restart Chrome.

Firefox:

1. Go to about:preferences.
2. Scroll to "Performance."
3. Uncheck "Use recommended performance settings."
4. Uncheck "Use hardware acceleration when available."
5. Restart Firefox.

If disabling hardware acceleration fixes the issue, it likely indicates a GPU driver problem. Updating your graphics drivers may allow you to re-enable it later.

When ChatGPT Works but Something Is Missing

Not every "ChatGPT not working" report is a failure. Chats that seem to have vanished, a thread that stops keeping context, and a model that forgets what you told it are three separate problems with three separate causes.

• Conversations look gone. They are almost always still there, just buried, because the sidebar loads only a slice of your history at a time. Our guide to finding and managing ChatGPT history covers recovering them, and finding one specific message handles the case where you know what was said but not where.
• A long thread starts losing the plot. That is the context window filling up, not a bug. The context window meter shows how close you are, and the character and word limit guide explains how much you can send in one message.
• ChatGPT forgets things it should remember. That is the memory feature, which is configurable and can be selectively cleared. See how to manage ChatGPT memory.

Frequently Asked Questions

Why is ChatGPT not working today?

There are only three causes worth checking. First, an OpenAI incident: status.openai.com lists it within minutes and nothing on your side fixes it. Second, your browser: a stale cache, an expired login cookie, or an extension that rewrites the page, which a private window exposes in one reload. Third, a limit: free and Go accounts hit message, upload, and image caps, and paid accounts hit rolling usage windows, in which case ChatGPT loads but refuses to answer until the window resets. Work through the ten fixes below in order and you will land on the cause within five minutes.

Is ChatGPT down right now, or is it just me?

Check status.openai.com first. If it lists an active incident or degraded performance, ChatGPT is down for everyone and the only fix is to wait, since outages usually clear within 30 minutes to a few hours. If the status page is green, the problem is local: clear your cache, test in incognito mode, and disable extensions one by one.

Why does ChatGPT show a blank screen?

A blank screen is almost always a stale browser cache or an extension conflict, not an outage. Clear your cache and cookies first, then reload ChatGPT in a private window. If the private window works, the cause is in your normal profile, so re-enable extensions one at a time until the blank screen returns.

Why does ChatGPT keep logging me out?

Repeated logouts come from expired authentication tokens, which happens when something clears your cookies automatically. The usual causes are a privacy extension, a browser set to wipe site data on exit, or switching between several devices. Disable automatic cookie clearing and allow cookies from both chatgpt.com and auth0.openai.com, then log in once more.

What does "Something went wrong" mean in ChatGPT?

It is a generic error covering server overload, a failed request, and a corrupted session, so it never points at one cause. Refresh the page first. If it persists, log out and back in, then clear your cache. When it only appears in one long-running conversation, start a fresh chat, because that thread has likely exhausted its context window.

Does AI Toolbox cause conflicts with ChatGPT?

No. AI Toolbox runs as a lightweight overlay that does not rewrite ChatGPT's core interface or intercept its API requests, which is what causes most extension conflicts. It is built to sit alongside ChatGPT without producing blank screens, slowdowns, or errors. Across 40,000+ active users holding a 4.6/5 Chrome Web Store rating, conflict reports are rare.

Why is ChatGPT slow even when nothing is broken?

Slowness is usually server-side load during peak hours, which no local change will fix. On your end, close spare tabs, disable heavy extensions, and confirm a stable connection. Switching from a high reasoning effort to a lighter one also returns answers faster. Our dedicated guide to a slow ChatGPT covers the rest.

Conclusion

Most ChatGPT issues boil down to three categories: server outages (wait it out), browser problems (clear cache or disable extensions), and network issues (check your connection). Working through the 10 fixes in this guide will resolve the vast majority of problems in minutes.
