If ChatGPT is not working, the problem may be caused by a temporary service outage, browser data, extensions, VPN settings, network filtering, login problems, or a conversation that has stopped responding.
You may see a blank page, endless loading, “Something went wrong,” network errors, login failures, or a response that stays stuck on generating.
QUICK ANSWER
If ChatGPT is not working, check the OpenAI status page first, refresh the page or start a new chat, clear browser cache and cookies, test an incognito window, disable browser extensions, turn off VPN or proxy services, try another browser or network, and contact OpenAI Support if the problem continues across multiple devices and networks.
Why Is ChatGPT Not Working?
ChatGPT problems generally fall into two groups:
Service-side problems
- Temporary service outage
- Elevated error rates
- Maintenance or infrastructure problems
Local problems
- Browser cache or cookies
- Browser extensions
- VPN or proxy
- Secure DNS or network filtering
- Login authentication problems
- Unstable internet connection
Important:
Check whether the problem affects everyone before changing your computer or browser settings. If OpenAI is experiencing an outage, local troubleshooting may not fix the problem.
1. Check the OpenAI Status Page
Start by checking whether ChatGPT is experiencing a known service problem.
The OpenAI status page reports incidents affecting services such as:
- ChatGPT
- OpenAI APIs
- Other OpenAI services
If an active incident is listed, the best solution may simply be to wait until the issue is resolved.
Tip:
If ChatGPT suddenly stops working on several devices at the same time, check service status before changing browser settings.
2. Refresh the Page or Start a New Chat
A temporary session problem can cause ChatGPT to stop responding.
Try:
- Reloading the page
- Starting a new conversation
- Closing and reopening the app
- Using a hard refresh on desktop
If one long conversation is slow or stuck while new conversations work normally, the issue may be limited to that conversation session.
Useful clue:
If a new chat works normally, you may not need to change your browser or network at all.
3. Clear Browser Cache and Cookies
Old browser data can interfere with web applications.
Clear the site data, cache, and cookies associated with ChatGPT, then restart the browser.
This is especially useful when:
- ChatGPT worked normally before
- The page suddenly became blank
- Login loops appear
- The interface does not load correctly
Note:
Clearing cookies may sign you out, so make sure you know which login method you normally use.
4. Try Incognito or Private Browsing
Open ChatGPT in an incognito or private browser window.
This can help rule out problems caused by:
- Stored cookies
- Cached site data
- Browser extensions
- Old authentication sessions
If ChatGPT works normally in private mode, the problem is probably related to your normal browser profile.
Diagnostic Tip:
Incognito mode is one of the fastest ways to separate an account problem from a browser-profile problem.
5. Disable Browser Extensions
Browser extensions can interfere with ChatGPT scripts, authentication, cookies, or network requests.
Pay special attention to:
- Ad blockers
- Privacy extensions
- Script blockers
- Security extensions
- Cookie-management tools
Disable extensions temporarily and reload ChatGPT.
If the problem disappears, enable the extensions again one at a time until you identify the conflict.
Useful clue:
If ChatGPT works in incognito mode but fails in your normal browser, an extension is one of the first things to investigate.
6. Turn Off VPN, Proxy, or Secure DNS
VPNs, proxies, security filters, and some DNS tools can interfere with ChatGPT connections.
Temporarily disable:
- VPN
- Proxy
- Secure DNS filtering
- Web protection tools
- Corporate network filtering
Then reload ChatGPT.
If it begins working, investigate the network or security tool before turning it back on.
Important:
On a company or school network, network administrators may control filtering settings that you cannot change yourself.
7. Try Another Browser, Device, or Network
Testing another environment helps identify where the problem is located.
Try:
- Another browser
- Another computer
- Your phone
- Mobile data instead of Wi-Fi
- Another Wi-Fi network
For example:
Works on mobile data but not Wi-Fi
The Wi-Fi network, router, ISP, or DNS configuration may be involved.
Works in Chrome but not another browser
The original browser profile or extensions may be responsible.
Simple rule:
Change one variable at a time so you can identify what actually fixes the problem.
8. Check Login Method and Contact Support
If the problem is specifically related to signing in, make sure you are using the same authentication method you originally used.
Possible methods include:
- Email login
- Microsoft
- Apple
- Organization SSO
Using a different method can cause authentication errors or lead you to a different account.
If ChatGPT still fails across several:
- Browsers
- Devices
- Networks
contact OpenAI Support and provide as much information as possible.
Useful troubleshooting details include:
- Error message
- Approximate time of the failure
- Browser and device
- Whether VPN was enabled
- Steps already tested
Recommended approach:
First determine whether the issue is a service outage, browser problem, network problem, or account problem. This is faster than repeatedly reinstalling apps or changing unrelated settings.
ChatGPT Stuck on Loading or Generating
If ChatGPT stays on “Generating,” “Thinking,” or a loading spinner:
- Wait briefly
- Stop generation and retry
- Start a new chat
- Refresh the page
- Check service status
- Try another network
If only one conversation is affected, start a new conversation before performing more aggressive troubleshooting.
ChatGPT Login Not Working
For login failures, check:
- Correct authentication method
- Browser cookies
- VPN or proxy
- Incognito mode
- Different network
- Temporary login restrictions
If you originally registered using Google, Microsoft, Apple, or an organization login, use that same method when signing in again.
Common Reasons ChatGPT Is Not Working
- Temporary OpenAI service incident
- Browser cache or cookie problem
- Browser extension conflict
- VPN or proxy interference
- Network or DNS filtering
- Wrong login method
- Long or stuck conversation
- Device-specific browser problem
Frequently Asked Questions
Why is ChatGPT not loading?
The cause may be an OpenAI service issue, browser cache, extensions, VPN, network filtering, or a temporary session problem.
Why does ChatGPT say “Something went wrong”?
This is a general error that can result from either a temporary server problem or a local browser or network issue.
Why does ChatGPT work on my phone but not my computer?
The problem is likely specific to the computer, browser, extensions, network, or cached data.
Can a VPN stop ChatGPT from working?
Yes. VPNs and proxies can sometimes interfere with authentication or stable network connections.
Should I create a new ChatGPT account?
No. Troubleshoot the existing login method and service connection first. Creating another account can make subscriptions and account data more confusing.
Final Checklist
- ✓ Check OpenAI service status
- ✓ Refresh or start a new chat
- ✓ Clear browser cache and cookies
- ✓ Try incognito mode
- ✓ Disable extensions
- ✓ Turn off VPN or proxy
- ✓ Test another browser, device, or network
- ✓ Verify login method and contact Support if needed
Bottom line:
When ChatGPT is not working, first check whether OpenAI is experiencing a service issue. If services are operating normally, troubleshoot the browser, cache, extensions, VPN, network, and login method systematically before contacting Support.
