Have you been getting an "Access Denied" error with the code 1020 when trying to use ChatGPT lately? I totally understand how frustrating that is – you‘re excited to have a conversation with this cutting-edge AI assistant, but some vague error message blocks you from chatting.
Not to worry! As an AI expert, I‘ve helped many users get ChatGPT working again after seeing this error. In this guide, I‘ll explain exactly why the ChatGPT access denied 1020 error happens and walk you through the steps to fix it.
Why Does the ChatGPT Error 1020 Access Denied Issue Happen?
The core reason you‘re seeing "Access Denied" is because ChatGPT is protected by Cloudflare‘s security system. Cloudflare analyzes traffic to sites like ChatGPT in order to block potential threats and abuse.
If your IP address exhibits any unusual or suspicious activity patterns, Cloudflare may flag it and deny access to ChatGPT with a 1020 error code. This could happen from:
- Sending a flood of requests too quickly from your IP.
- Your network connection appearing insecure or compromised.
- Using a shared VPN IP that was previously flagged for abuse.
- Browser privacy extensions that interfere with Cloudflare protections.
Now that we know why Access Denied 1020 happens, let‘s get into the solutions so you can start chatting with ChatGPT again!
Use a VPN to Change Your IP Address
The quickest and most effective fix is to use a trusted VPN (virtual private network) service to change your IP address.
A VPN gives you a different, ‘clean‘ IP that isn‘t associated with any previous blocks or restrictions. Here‘s how to set it up:
- Sign up for a top-rated VPN like ExpressVPN, NordVPN, Surfshark, etc.
- Install the VPN software on the device you use ChatGPT on.
- Connect to a server located in a country where ChatGPT access isn‘t blocked.
- Once connected, try loading ChatGPT again – it should now work!
For example, if you connect to a VPN server in the USA, you‘ll get an American IP address that provides full access to ChatGPT.
Using a VPN allows access to ChatGPT by assigning you a new IP address
If this fixes your access denied issue, you‘ll need to use the VPN each time you want to access ChatGPT without issues.
Some key tips for using a VPN with ChatGPT:
- Connect to a server that‘s geographically close for faster speeds.
- If one VPN IP stops working, switch to another server.
- Disable VPN when not using ChatGPT to maintain performance.
Clear Your Browser Cache and Data
Outdated browser data can also sometimes interfere with ChatGPT access, so clearing it is another good troubleshooting step.
Here‘s how to clear browser cache/data in the major browsers:
Chrome
- Click the 3 vertical dots in the top right corner.
- Go to Settings > Privacy and security > Clear browsing data.
- Select "All time" for the time range.
- Check the boxes for "Browsing history," "Cookies and other site data," and "Cached images and files."
- Click "Clear data."
Firefox
- Click the 3 horizontal lines in the top right corner.
- Go to Options > Privacy & Security > Clear Data.
- Select "Caches" and check all other boxes.
- Click "Clear."
Safari
- Go to Preferences > Privacy > Manage Website Data.
- Click "Remove All."
Make sure to clear all cached images, files, cookies and site data
Once your browser data is wiped, restart the browser and try loading ChatGPT again. Often a fresh slate resolves underlying issues.
Disable Browser Extensions Temporarily
Some third-party browser extensions have been known to interfere with ChatGPT access, so disabling them is worth trying.
Follow these steps to disable all extensions:
Chrome
- Click the 3 dots in the top right corner.
- Go to More tools > Extensions.
- Toggle the switch off for each extension.
Firefox
- Click the 3 lines in the top right corner.
- Go to Add-ons > Extensions.
- Toggle the switch off for each extension.
Safari
- Go to Preferences > Extensions.
- Uncheck the box next to each extension.
Reload ChatGPT. If access is restored, turn extensions back on one-by-one until you identify the problematic addon, then remove it.

Why Does ChatGPT Access Get Blocked in the First Place?
To prevent this headache in the future, it helps to understand exactly why ChatGPT access gets blocked at the IP level.
Cloudflare has seen massive growth in traffic to ChatGPT – over 13 million visits per day up 450% since ChatGPT launched in November 2022. And with skyrocketing demand comes potential for abuse.
To maintain security, Cloudflare actively analyzes traffic and connections to ChatGPT for signs of:
- Automated bots – programs sending excessive requests instead of real humans.
- Scraping – people harvesting or copying ChatGPT‘s responses at scale.
- Spam – posting dangerous links, profanity, or other abusive content.
When an IP address sends unusual traffic like this, access gets restricted to protect ChatGPT. Legitimate users can get caught up in this like in the following examples:
- You send a ton of rapid inputs that may appear like a bot.
- Your network has lax security or got compromised by malware.
- The VPN you use was already banned for previous abuse.
Luckily, the solutions in this guide will override these IP blocks so you can chat freely and avoid future access denied headaches.
Recap: Fixing ChatGPT Error 1020 Access Denied
To recap, here are the steps to resolve ChatGPT access denied error 1020:
-
Use a VPN – Connect to a server in an unrestricted country to change your IP address.
-
Clear Browser Data – Wipe cached images, files, cookies and site data.
-
Disable Extensions – Switch off all add-ons temporarily to check for conflicts.
-
Contact OpenAI Support – Explain your issue and provide key details for personalized help.
