As we know, encountering the ‘Access Denied 1020’ error code can be a frustrating experience. This error message may appear on your screen when you try to log into ChatGPT or access certain resources and features 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 use to protect our site against 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 an Access Denied 1020 error.

Why do I get the Access Denied 1020 error?

There are several reasons why you might get the Access Denied 1020 error when trying to access ChatGPT. Some of the most common reasons are:

  • Your IP address is blacklisted: Cloudflare maintains a list of IP addresses that have been flagged for suspicious activity or associated with malicious behavior. If your IP address is on this list, access to our site will be blocked.
  • Your network is being blocked: If you are accessing ChatGPT from a corporate or public network, the network administrator may have implemented a security measure that blocks your access to our site.
  • Your browser sends suspicious requests: If your browser sends 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 get an Access Denied 1020 error when you try to access ChatGPT, here are some steps you can take to resolve this issue:

Check your IP address:

The first step is to check if your IP address is blacklisted by Cloudflare. You can do this by visiting the Cloudflare website and entering your IP address in the search box. If your IP address is blacklisted, 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 be caused by corrupt or outdated browser data. Clearing your browser’s cache and cookies can often solve this problem. To do this, go to your browser settings and look for the option to clear your cache and cookies.

Disable your VPN or proxy:

If you use 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, please contact ChatGPT Support for assistance. Our support team can help you determine the cause of the error and provide you with further instructions on how to resolve it.

Check your Firewall settings:

Sometimes your local firewall settings can interfere with ChatGPT’s WAF, resulting in an access denied error. Check your firewall settings and make sure ChatGPT is not blocked. You may need to add ChatGPT to your firewall 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 could be interfering 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 opening ChatGPT in incognito mode, which will disable browser extensions, cache and cookies.
