If ChatGPT is not working for you right now, you’re not alone. Millions of users hit these frustrating roadblocks daily, from login failures and infinite redirect loops to the AI simply going silent mid-conversation. The good news? Almost every ChatGPT error has a fix — and most of them take less than five minutes.
In this guide, we’ll walk through every major ChatGPT error you’re likely to encounter: why it happens, what it means, and exactly how to resolve it. Whether you’re on a desktop browser, a mobile phone, or hitting a wall with the API, this is your definitive troubleshooting resource.
Let’s get ChatGPT working again.
Why Is ChatGPT Not Working? The Most Common Causes
Before jumping into specific fixes, it helps to understand what’s typically behind a broken ChatGPT session. The culprits usually fall into a few categories:
- Server-side outages — OpenAI’s infrastructure occasionally goes down under heavy load
- Browser or app issues — outdated cache, conflicting extensions, or stale cookies
- Account or authentication problems — session tokens that expired or got corrupted
- Network and DNS issues — particularly common on mobile or corporate Wi-Fi
- Rate limits — hitting usage caps on free or Plus plans
Knowing the category helps you skip irrelevant steps and zero in on the real problem fast.
How to Check If ChatGPT Is Down (Before You Do Anything Else)
The very first step — before clearing caches or reinstalling apps — is to check whether the issue is on OpenAI’s end, not yours.
How to verify:
- Visit OpenAI’s official status page — it lists real-time service health for ChatGPT, the API, and plugins.
- Check Downdetector’s ChatGPT page for crowd-sourced outage reports.
- Search Twitter/X for “ChatGPT down” — if it’s a widespread outage, it’ll trend within minutes.
If OpenAI confirms an incident, there’s nothing to fix on your end. Bookmark the status page and wait it out.
If the status page shows all systems green, the problem is local — and the fixes below will solve it.
ChatGPT Not Responding: Step-by-Step Browser Fixes
When ChatGPT is not responding — messages send but no reply comes, or the interface freezes — the browser is almost always the first place to investigate.
1. Hard Refresh the Page
A soft refresh (F5) reloads the page but keeps cached assets. A hard refresh forces the browser to fetch everything fresh.
- Windows/Linux:
Ctrl + Shift + R - Mac:
Cmd + Shift + R
This alone resolves roughly 20% of “ChatGPT not responding” cases.
2. Clear Your Browser Cache and Cookies
Stale cached data is one of the top culprits. Here’s how to clear it in Chrome:
- Click the three-dot menu → Settings
- Go to Privacy and Security → Clear browsing data
- Select Cookies and other site data + Cached images and files
- Set time range to All time
- Click Clear data, then reload ChatGPT
Repeat in Firefox via Ctrl + Shift + Delete or in Safari under Develop → Empty Caches.
3. Disable Browser Extensions
Ad blockers, privacy shields, and script blockers are notorious for interfering with ChatGPT’s real-time streaming. Open an Incognito/Private window — which disables extensions by default — and try ChatGPT there. If it works, an extension is your culprit. Disable them one by one to identify which.
4. Try a Different Browser
If Chrome is failing, try Firefox, Edge, or Brave. This instantly tells you whether it’s a browser-specific problem.
5. Check Your Internet Connection
Run a quick speed test at fast.com. ChatGPT’s streaming responses require a stable connection; packet loss or latency spikes above 200ms can cause the response to stall mid-generation.
ChatGPT Too Many Redirects: What It Means and How to Fix It
The “ChatGPT too many redirects” error is particularly baffling because it sounds like a server problem — but it’s almost always a local browser issue.
This error occurs when your browser gets trapped in a redirect loop: ChatGPT tries to redirect you to a login page, which redirects back to ChatGPT, which redirects again — infinitely. The browser gives up and throws the error.
Why It Happens
- Corrupted or expired session cookies
- Browser security settings blocking third-party cookies
- A VPN or proxy interfering with authentication redirects
- Conflicting browser extensions
The Fix (Works 90%+ of the Time)
Step 1: Clear cookies specifically for chat.openai.com and openai.com
- In Chrome:
Settings → Privacy → Cookies → See all site data → search "openai" → Delete
Step 2: Disable your VPN temporarily. Authentication flows are sensitive to IP changes.
Step 3: If you use strict cookie-blocking settings, whitelist openai.com and chat.openai.com.
Step 4: Log out fully, clear cookies again, then log back in fresh.
This sequence resolves the redirect loop in nearly every case.
Chat GPT Not Working on Phone: Mobile-Specific Fixes
Mobile is where ChatGPT errors get most frustrating — especially when you’re mid-conversation and the app or browser just stops cooperating. Here’s how to tackle Chat GPT not working on phone scenarios across both iOS and Android.
Fix for the ChatGPT Mobile App
On iPhone (iOS):
- Force-close the app (swipe up from App Switcher)
- Go to Settings → General → iPhone Storage → ChatGPT → Offload App
- Reinstall from the App Store
- If issues persist, go to Settings → ChatGPT → toggle off Background App Refresh, then re-enable it
On Android:
- Go to Settings → Apps → ChatGPT → Storage → Clear Cache (not Clear Data, which logs you out)
- If clearing cache doesn’t work, try Clear Data and log back in
- Check for app updates in the Play Store — many mobile bugs are patched in minor version updates
Fix for ChatGPT in a Mobile Browser
If you’re using Safari or Chrome on mobile instead of the app:
- Safari on iPhone: Settings → Safari → Clear History and Website Data
- Chrome on Android: Chrome menu → History → Clear browsing data → Cookies and cached files
Also check that you’re not in Low Power Mode — some aggressive battery-saving configurations throttle JavaScript-heavy web apps.
Check Network Permissions
On both iOS and Android, confirm ChatGPT has network access:
- iOS: Settings → ChatGPT → ensure “Mobile Data” is enabled
- Android: Settings → Apps → ChatGPT → Permissions → ensure network access is unrestricted
ChatGPT Login Not Working: Account and Authentication Errors
If you can’t even get past the login screen, here are the most likely causes and fixes.
“Unable to Log In” or Infinite Login Loop
This is often the same redirect issue described above — clear cookies for openai.com and try again in Incognito mode.
Email Not Recognized
If you signed up via Google or Microsoft SSO, you may not have a password set. Use “Continue with Google” instead of typing your email directly.
Account Temporarily Locked
After multiple failed login attempts, OpenAI may temporarily lock your account. Wait 15–30 minutes, then try again. If you’ve forgotten your password, use the “Forgot password” link — don’t keep attempting logins.
Two-Factor Authentication Issues
If you’ve lost access to your authenticator app, use a backup code. If you don’t have backup codes, contact OpenAI Support directly with your account email.
ChatGPT Not Working Fix for Specific Error Messages
Here’s a quick-reference table for the most common error messages and what to do about them:
| Error Message | Likely Cause | Fix |
|---|---|---|
| “Something went wrong” | Generic server or session error | Refresh, clear cookies, retry |
| “Too many requests” | Rate limit hit (free tier) | Wait 1 hour or upgrade to Plus |
| “Network error” | Connection dropped mid-stream | Check internet, try wired connection |
| “Unable to load conversation” | Corrupted conversation history | Start a new chat |
| “ChatGPT is at capacity” | Server overload | Retry in off-peak hours or use Plus |
| “Access denied” | VPN/IP block or account issue | Disable VPN, check account status |
| “Too many redirects” | Cookie/session conflict | Clear cookies, disable VPN |
Why Is My ChatGPT Not Working Even After All These Fixes?
If you’ve tried everything above and ChatGPT is still broken, consider these less-obvious culprits:
Your ISP or Network Is Blocking OpenAI
Some corporate networks, schools, and ISPs in certain regions block or throttle OpenAI’s servers. Test on a completely different network — your phone’s mobile data is the fastest way to verify this.
Your Account Has Been Suspended
OpenAI does suspend accounts that violate their usage policies. If you suspect this, log into platform.openai.com and check for any account notifications.
You’re Using an Unofficial ChatGPT App
There are dozens of fake or unofficial “ChatGPT” apps on both the App Store and Play Store. The only official apps are published by OpenAI — verify the developer name before trusting any app with your credentials.
DNS Issues
Try changing your DNS to Google (8.8.8.8) or Cloudflare (1.1.1.1) — some ISP DNS servers fail to resolve OpenAI domains correctly, especially after outages.
Pro Tips to Prevent ChatGPT Errors in the Future
Prevention beats troubleshooting. Here are habits that will save you headaches:
- Bookmark the status page: status.openai.com — check it first whenever something breaks
- Use the official app or chat.openai.com — not third-party wrappers
- Keep your browser updated — ChatGPT uses modern web APIs that older browsers don’t support well
- Don’t use ChatGPT over public Wi-Fi without a reliable VPN — but disable the VPN when logging in
- Subscribe to OpenAI’s status page alerts — you’ll get an email the moment an incident is declared
Conclusion: Get Back to Using ChatGPT Without the Frustration
ChatGPT errors are rarely permanent. Whether you’re dealing with ChatGPT not responding, a maddening redirect loop, or the app going silent on your phone, the fixes are almost always within your control — and fast to implement.
To recap the essentials: check the status page first, clear cookies and cache, test in Incognito mode, and rule out VPN or extension conflicts. For mobile, verify app permissions and confirm you’re running the official OpenAI app. And for persistent issues, a DNS switch or network change will often reveal whether your ISP is the real culprit.
