Now that we have discussed some common issues that s may face when ChatGPT is not working, let’s explore some solutions to fix them.

Check Internet Connection 4b5k1p

Check your internet connection first when experiencing any issues with ChatGPT. Your internet connection should be stable, and your device should be connected to the internet. If you are having trouble accessing an online service, open a web page to check your internet connection.

Clear Browser Cache and Cookies 504e1j

Sometimes, ChatGPT may have not working issues due to a corrupted browser cache and cookies. It may help to clear the cache and cookies of your browser in order to resolve this issue. To do this,

1. Open the Chrome browser and tap on the three-dot button at the top-right corner of the screen.
2. Afterward, simply tap on the settings button.
3. Now, hit the Privacy and Security section.
4. Now, tap on the “Clear browsing data” option, and select “Cache and Cookies.”
5. Then, hit the Clear Data button.

Disable Ad Blocker and VPN 2v6y53

Certain ad blockers or VPN extensions may interfere with ChatGPT’s functionality—especially if they block JavaScript or route traffic through suspicious IPs.

In 2025, some advanced VPNs and browser privacy tools may also trigger Cloudflare security blocks, resulting in Error 1020. If ChatGPT doesn’t load or shows restricted access:

• Temporarily disable your VPN or proxy service.
• Pause ad blockers like uBlock Origin or AdGuard.
• Refresh the page or restart your browser after disabling.

Once ChatGPT is working again, you can selectively enable your privacy tools to identify the one causing issues.

Try a Different Browser 302j4l

If ChatGPT isn’t loading or responding on your current browser, try using an alternative browser such as Firefox, Edge, Brave, or Safari. Some browser extensions or outdated configurations may affect compatibility.

💡 In 2025, Brave Shields and Safari’s Intelligent Tracking Protection have been known to occasionally block ChatGPT scripts. Temporarily disable such features to test.

Restart ChatGPT 6h3n5r

If ChatGPT is lagging or unresponsive, try restarting your session:

• Close the browser tab or app window completely.
• Reopen a new tab or app session and sign in again.
• You can also log out of your OpenAI and log back in for a full reset.

This clears temporary session bugs and often fixes problems with message delivery or rendering.

Report the Issue to OpenAI Team 364j40

If none of the solutions above work, reach out to OpenAI Help with a description of the issue. Include a screenshot or exact error message (like “Error 1020” or “Internal Server Error”) to help the team diagnose the problem faster.

Use the ChatGPT Mobile or Desktop App 3x5m4g

In 2025, ChatGPT’s official mobile and desktop apps offer better performance than browser versions, especially during peak hours. If the web app isn’t loading or keeps showing errors, switch to the official app:

• the ChatGPT app from the App Store or Google Play.
• Or install the desktop version available at https://openai.com/chat (for Mac and Windows).

These apps often by browser-related issues and are less likely to trigger Cloudflare or session-related errors.

Check the OpenAI Status Page 6h452d

Sometimes the issue isn’t on your end. Before troubleshooting further, check if ChatGPT is down for everyone:

• Visit the official OpenAI Status Page: https://status.openai.com

If there’s a yellow or red alert, the problem is likely server-side. You’ll need to wait for OpenAI to fix it before ChatGPT becomes stable again.

Switch to GPT-3.5 if GPT-4o is Lagging 6uo1f

If you’re a ChatGPT Plus and GPT-4o is slow or giving “high demand” errors, try switching to GPT-3.5:

• Open ChatGPT.
• Click on the GPT version selector at the top.
• Choose GPT-3.5 temporarily for quicker responses.

GPT-3.5 may have fewer capabilities, but it’s usually faster during server overloads.
