How To Fix ChatGPT Access Denied 1020


At ChatGPT, we understand the frustration that comes with encountering access issues on our platform. One of the most common problems users face is the Access Denied 1020 error, which can prevent them from accessing our site. In this article, we will explain what this error means and provide steps to fix it.

We know that coming across an "Access Denied 1020" error code can be a frustrating experience. This error message may appear when attempting to log in to ChatGPT or access certain resources and functions on the platform. This error code indicates that the Cloudflare Web Application Firewall (WAF) has blocked access from your IP address due to suspicious or malicious activity.

What is the Access Denied 1020 Error?

The Access Denied 1020 error is a security measure implemented by Cloudflare, a third-party service we utilize to protect our site from online threats. When Cloudflare detects suspicious activity or an attempt to access our site from a blacklisted IP address, it will block the request and return the Access Denied 1020 error message.

Why Am I Getting the Access Denied 1020 Error?

There are several reasons why you might be encountering the Access Denied 1020 error when trying to access ChatGPT. Some common reasons include:

  • Your IP address has been blacklisted: Cloudflare maintains a list of IP addresses flagged for suspicious activity or associated with malicious behavior. If your IP address is on this list, you will be blocked from accessing our site.
  • Your network is being blocked: If you're accessing ChatGPT from a corporate or public network, the network administrator may have implemented a security measure that blocks access to our site.
  • Your browser is sending suspicious requests: If your browser is sending requests that appear to be automated or malicious, Cloudflare may block your access to our site.

How To Fix the Access Denied 1020 Error?

If you are encountering the Access Denied 1020 error when trying to access ChatGPT, here are some steps you can take to resolve it:

Check Your IP Address:

The first step is to check whether your IP address is on Cloudflare's blacklist. You can do this by visiting the Cloudflare website and entering your IP address in the search box. If your IP address is on the blacklist, you will need to contact your ISP to resolve the issue.

Clear Your Browser's Cache and Cookies:

Sometimes, the Access Denied 1020 error can occur due to corrupted or outdated browser data. Clearing your browser's cache and cookies can often resolve this issue. To do this, go to your browser's settings and find the option to clear your cache and cookies.

Disable Your VPN or Proxy:

If you're using a VPN or proxy to access the internet, try disabling it and accessing ChatGPT directly. Some VPNs and proxies can trigger the Access Denied 1020 error, so disabling them may resolve the issue.

Contact ChatGPT Support:

If none of the above steps resolve the issue, contact ChatGPT support for assistance. Our support team will help you identify the cause of the error and provide further instructions on how to resolve it.

Check Your Firewall Settings:

Sometimes, your local firewall settings may interfere with ChatGPT's WAF, resulting in an "access denied" error. Check your firewall settings and ensure that ChatGPT is not blocked. You may need to add ChatGPT to your firewall's whitelist.

Check for Malware or Adware:

Malware or adware on your device can cause the Cloudflare WAF to flag your IP address as a security risk. Run a malware or adware scan on your device to identify and remove any threats.

Disable Antivirus or Security Software:

Antivirus or security software on your device may interfere with ChatGPT's WAF, leading to an "access denied" error. Temporarily disable your antivirus or security software and try accessing ChatGPT again.

Use Incognito Mode:

Sometimes, your browser's cache or cookies can interfere with ChatGPT's WAF, causing an "access denied" error. Try accessing ChatGPT in incognito mode, which disables browser extensions, cache, and cookies.


Encountering the ChatGPT Access Denied 1020 error can be frustrating, but it is a necessary security measure to protect our site and users.
