ChatGPT goes down, freezes, throws errors, and stops responding more often than OpenAI would like to admit. Whether you're seeing "ChatGPT is at capacity," getting blank responses, or hitting a login loop, here's what actually fixes it — ranked from easiest to most involved.

ℹ️
Before troubleshooting, check status.openai.com — if ChatGPT is down globally, nothing you do locally will help. Wait it out, then try these fixes once the service recovers.

Fix 1: Check If ChatGPT Is Down (30 Seconds)

Half of all "ChatGPT not working" complaints are actually OpenAI server outages. Before you spend time troubleshooting your device, verify whether it's a global issue:

  • Go to status.openai.com — OpenAI's official status page
  • Check downdetector.com/status/chatgpt — user-reported outage tracker with real-time map
  • Search "ChatGPT down" on Twitter/X — outage reports surface within minutes

If the status page shows an incident or degraded performance, wait 15–30 minutes and try again. OpenAI's infrastructure team usually resolves partial outages quickly.

Fix 2: Hard Refresh or Clear Browser Cache

ChatGPT loads as a React app in your browser, and cached files sometimes break after OpenAI pushes an update. This is one of the most common causes of blank chat screens, disappeared conversations, and the "Something went wrong" error.

Hard refresh (Windows/Linux): Ctrl + Shift + R Hard refresh (Mac): Cmd + Shift + R Hard refresh (any browser): Hold Shift while clicking the Refresh button

If that doesn't work, clear the cache for chatgpt.com specifically:

  • Chrome: Settings → Privacy → Clear browsing data → check "Cached images and files" → select "Last 7 days" → Clear
  • Safari: Develop → Empty Caches (enable Develop menu in Safari → Preferences → Advanced first)
  • Firefox: Ctrl+Shift+Delete → check Cache → Clear

Fix 3: Try a Different Browser or Incognito Mode

Extensions, saved logins, and browser settings frequently break ChatGPT. A quick test: open ChatGPT in an incognito or private window (Ctrl+Shift+N in Chrome, Ctrl+Shift+P in Firefox). If it works in incognito but not normally, the culprit is an extension or cookie.

Common extension conflicts in 2026:

  • Ad blockers (uBlock Origin, AdGuard) — sometimes block OpenAI's API calls
  • Dark mode extensions that inject CSS
  • Privacy badger or similar tracking blockers
  • Browser translation extensions that rewrite page content

Disable extensions one by one to find the offender, then whitelist chatgpt.com in that extension's settings.

Fix 4: Log Out and Log Back In

ChatGPT sessions expire, and a stale auth token causes the chat interface to stop working without an obvious error message. Logging out and back in refreshes your session completely.

  1. Click your profile icon (bottom left on desktop)
  2. Select Log out
  3. Close the tab entirely
  4. Reopen chatgpt.com and log in again

If you use Google or Microsoft login, make sure your Google/Microsoft account isn't logged out in another tab — that can break ChatGPT's SSO session silently.

Fix 5: Switch to a Different Network (VPN Users Take Note)

OpenAI blocks known VPN exit nodes, Tor exit nodes, and some data center IP ranges. If you're using a VPN and ChatGPT isn't loading or shows a "This service is not available in your country" message, try:

  • Turning off your VPN temporarily
  • Switching to a different VPN server (residential IPs work better than data center IPs)
  • Using a mobile hotspot to test if the issue is your home network

Conversely, if you're in a region where ChatGPT has restrictions, a VPN with a US or EU server is often the fix.

**#1 cause** of ChatGPT errors: OpenAI server outages (check status.openai.com first)
**#2 cause**: stale browser cache or broken session token
**#3 cause**: VPN or network blocking

Fix 6: The "ChatGPT is at Capacity" Error

This error means OpenAI's servers are overloaded — more users than the system can handle at that moment. Your options:

  1. Wait and retry — Demand spikes during business hours (9 AM–6 PM US Eastern). Try again in 15–30 minutes.
  2. Upgrade to ChatGPT Plus — Paid users get priority access even during high-traffic periods. If you regularly hit this error, the $20/month is worth it.
  3. Use the API instead — platform.openai.com has separate capacity from the consumer chatgpt.com. New accounts get free credits.
  4. Try Claude or Gemini — When ChatGPT is overloaded, claude.ai and gemini.google.com are reliable free alternatives with comparable capability.

Fix 7: App-Specific Fixes (iOS, Android, Desktop)

iOS ChatGPT app not working:

  • Force-close the app: swipe up from home bar, swipe the ChatGPT card away
  • Update the app: App Store → your profile icon → scroll to ChatGPT → Update
  • Delete and reinstall — this clears all local cache including corrupted data
  • Check iOS Settings → ChatGPT → ensure Cellular Data is enabled if not on Wi-Fi

Android ChatGPT app not working:

  • Go to Settings → Apps → ChatGPT → Storage → Clear Cache (don't clear Data, which logs you out)
  • Force stop → reopen
  • Update the app via Google Play

Desktop app not working:

  • The ChatGPT desktop app (macOS and Windows, launched 2024) has its own update cycle separate from the web app. Check for updates within the app settings.
  • On macOS: quit completely (Cmd+Q, not just close window) and reopen
  • On Windows: check Task Manager to ensure the app isn't running in background before relaunching

Fix 8: Specific Error Messages and What They Mean

Key Facts
  • "Something went wrong. Please try again" — Usually a temporary server error; wait 60 seconds and retry
  • "There was an error generating a response" — Mid-response failure; click Regenerate or start a new chat
  • "Network error" — Your internet connection dropped during the response; check your Wi-Fi or cellular signal
  • "You've reached the message limit" — Free tier cap; wait for the next hour window or upgrade to Plus
  • "ChatGPT is at capacity right now" — Server overload; wait or use an alternative
  • "Unable to load conversation" — Old conversation data corrupted; open a new chat instead
  • Blank white screen on load — 99% of the time this is a cache issue; hard refresh or incognito first

When None of This Works

If you've tried every fix and ChatGPT is still broken specifically for your account:

  1. Try a different device — eliminates local hardware/software as the variable
  2. Check if your account was flagged — OpenAI can suspend accounts that violate terms. Check your email for a notice from OpenAI.
  3. Contact OpenAI support — help.openai.com → Submit a request. Response times are 24–72 hours for free users; Plus users get faster support.
  4. Create a new account — If you believe your account is clean and the old one isn't fixable, a fresh account with the same email on a new Google account is the nuclear option.

      The Bottom Line

      Ninety percent of ChatGPT problems resolve with three steps: check the status page, hard refresh your browser, and log out then back in. Extensions and VPNs cause most of the remaining cases.

      For frequent outage issues, ChatGPT Plus ($20/month) provides priority access during peak load — the single most effective way to avoid the "at capacity" error if you rely on ChatGPT for work.
