AI Tool Not Working? Quick Troubleshooting Guide
Step-by-step troubleshooting for when an AI chatbot, image generator, or AI app stops working. Covers browser issues, account problems, network checks, and how to tell if it’s a platform outage.
Step 1 — Check for a Known Outage First
Before troubleshooting your local setup, check whether the AI tool you’re trying to use is experiencing a known platform-wide outage. This saves time: if the tool is down for everyone, no amount of local troubleshooting will fix it. Visit the AI Down Status homepage and look for your tool in the status dashboard, or check the specific tool’s status page:
Step 2 — Browser and Extension Checks
Browser-related issues cause a significant proportion of AI tool failures that are mistaken for platform outages. Browser extensions, cached data, and outdated JavaScript bundles are the most common culprits.
- 1Try an incognito / private window — this disables most extensions and uses fresh session data. If the AI tool works in incognito, the issue is with your regular browser profile.
- 2Disable browser extensions — ad blockers (uBlock Origin, AdBlock Plus), privacy extensions (Privacy Badger, Ghostery), and VPN extensions commonly interfere with AI tools. Disable all extensions and test again.
- 3Clear browser cache and cookies — go to browser settings, clear cache and cookies for the AI tool’s domain, then reload. Stale cached JavaScript bundles cause silent failures.
- 4Try a different browser — if Chrome is broken, try Firefox or Edge. Browser-specific bugs do occur, and testing another browser quickly confirms whether the issue is browser-specific.
- 5Check browser console for errors — press F12, go to the Console tab, reload the page, and look for red error messages. CSP violations, CORS errors, or failed script loads can cause complete functionality failures.
Step 3 — Account and Login Checks
Authentication and subscription issues account for a large share of “AI not working” reports, particularly for paid AI services.
- 1Sign out and sign back in — expired or corrupted session tokens cause access failures. A fresh sign-in regenerates your auth token and often restores access.
- 2Check your subscription status — for paid AI tools (ChatGPT Plus, Claude Pro, etc.), go to your account billing settings and confirm your subscription is active and payment method is valid.
- 3Check if you hit a usage limit — most AI tools have message limits per hour or day. ChatGPT, Claude, and others impose per-model usage caps. Exhausting your limit produces error messages similar to outage errors.
- 4Verify you’re on the correct account — if you have multiple accounts (personal vs. work), confirm you’re signed into the one with the active subscription.
- 5Try password reset if login fails — if you cannot sign in at all, use the forgot password flow to confirm your credentials are working correctly before assuming a platform issue.
Step 4 — Network and Device Checks
Network problems can cause AI tools to fail even when the platform is fully operational. Corporate networks, VPNs, and restrictive firewall configurations are common network causes of AI tool failures.
- 1Try a different network — switch from WiFi to mobile data, or vice versa. If the AI tool works on mobile data but not WiFi, your router or ISP is interfering.
- 2Disable VPN or proxy — VPNs can route your traffic through IP ranges that AI providers rate-limit or block. Disable your VPN and test directly.
- 3Check corporate firewall settings — workplace networks often block or throttle AI tool domains. IT administrators may have restricted access. Try from a personal network or mobile data to confirm.
- 4Try a different device — test on your phone, tablet, or another computer. If it works elsewhere, the issue is specific to your primary device’s network or software configuration.
- 5Restart your router — if all other devices on your home network also cannot access the AI tool, restarting your router can resolve local DNS caching issues.
Step 5 — Mobile App Specific Checks
If you are using an AI tool’s mobile app and it stops working, app-specific issues may be separate from browser-based problems.
- 1Force close and reopen the app — clear the app from your task switcher and relaunch it to force a fresh connection to the AI service.
- 2Check for app updates — an outdated app version may be incompatible with recent API changes. Update to the latest version through the App Store or Google Play.
- 3Check app permissions — some AI apps require microphone, camera, or storage permissions that may have been revoked. Go to your device’s app settings and verify permissions are correct.
- 4Try the web version — if the mobile app is broken, try the same AI tool in your mobile browser. If the web version works, the issue is app-specific rather than platform-wide.
- 5Clear app cache — in Android app settings, you can clear the app’s cache without uninstalling it. On iOS, uninstalling and reinstalling the app clears its data.
How to Tell If It’s a Platform-Wide Outage vs. Your Issue
🔴 Signs it’s a platform-wide outage
- Fails in incognito and with extensions disabled
- Fails on multiple devices and networks
- Multiple users on different ISPs reporting same issue
- Error appears immediately without submitting any request
- Other AI tools are also showing problems simultaneously
🟡 Signs it’s your browser, account, or network
- Works in incognito but not normal browser window
- Works on mobile data but not WiFi
- Works on a different device or account
- Your usage limit or character quota is exhausted
- Issue followed a browser update, extension install, or VPN change
AI Tool Not Loading — Specific Error Messages
Different AI error messages point to different underlying problems. Here is a quick guide to common AI tool error messages and what they typically indicate:
“Something went wrong”
Generic backend error — can be server-side or session-related. Try signing out and back in first, then check for a platform outage.
Error 429
Too Many Requests — you have hit a rate limit. Wait a few minutes or switch to a lower-usage model tier. This is NOT an outage.
Error 503
Service Unavailable — the server cannot handle the request right now. Likely a real service degradation. Check AI Down Status for confirmation.
“At capacity”
The service is overloaded. Usually resolves within minutes. Wait and retry, or try at a lower-traffic time such as early morning.
“Request timed out”
Either a network timeout on your end or the server took too long to respond. Check your internet connection and retry with a shorter prompt.
“Invalid API key”
For developers — your API key has been revoked, expired, or has billing issues. Check your API key status in the provider’s developer dashboard.
❓ Frequently Asked Questions
This pattern almost always indicates a local issue on your computer rather than a platform problem. Common causes include a browser extension blocking the AI tool, cached data that needs clearing, a firewall or security software on your computer blocking the connection, or an outdated browser version. Try clearing your computer’s browser cache and disabling extensions as a first step.
Slow responses without errors usually indicate degraded performance on the server side rather than a full outage. This is common during peak hours when servers are under high load. Slow responses can also be caused by using a larger, more capable model (which takes longer to generate), or by using the service during a high-demand event such as a product launch. Check the AI Outage Tracker for reported degradation events.
Only contact support if: (1) the issue persists after trying all troubleshooting steps in this guide, (2) you have had credits or charges deducted for a failed service, or (3) your account appears locked or suspended. For platform-wide outages, support teams receive thousands of reports simultaneously and cannot provide individual resolutions — waiting for the outage to resolve is usually faster than contacting support during an active incident.
Yes. Some antivirus and security software products include web filtering that can block or throttle connections to AI services. This is more common in corporate security tools but can also affect consumer antivirus products. Try temporarily disabling your security software’s web filtering to test, and if that fixes the issue, add the AI tool’s domain to your security software’s allow list.
