What Is the Cloudflare Error 1020 & How to Fix It?

Cloudflare Error 1020 Access Denied is a block that stops you from accessing a website. It affects visitors who trip a security wire and site owners who might have set their rules too tightly. It happens because a firewall or Web Application Firewall (WAF) rule denies the request based on the site’s security policy.

We’ll help you understand why the error occurs and how to fix it quickly for both website owners and visitors.

Common Causes of Cloudflare Error 1020 Access Denied

Several things can trigger the block on a site protected by Cloudflare:

• Bad IP reputation. Your IP address has a history of spam or suspicious behavior.
• Browser issues. Corrupt cookies or cache can confuse the server.
• Strict firewall rules. The site owner blocked your country or specific actions.
• Low-quality VPN or proxy use. The security system flagged your masked IP as suspicious.
• Violating custom security logic. Your request pattern matched a specific rule set by the site admin.

If you need to bypass the error message, you may want to consider getting a high-quality residential proxy instead of relying on free solutions that are often heavily abused and unreliable.

How to Fix Cloudflare Error 1020 as an Administrator

If you’re on the administration side, the ‘Access Denied’ (Error Code 1020) fix is relatively simple since it’s usually caused by firewall rules. You can go to the Cloudflare admin panel and look at the event log, which you can find under ‘Firewall’ and ‘Events’.

There should be an event that triggered the Error 1020 Access Denied, and the rule that was violated should be mentioned as well. If it’s not a security-critical or otherwise important rule, you can simply remove it, and you shouldn’t be getting any more 1020 ‘Access Denied’ errors.

Alternatively, you can tinker with existing firewall rules instead of outright disabling one of them. It’s possible that the rule, which is preventing access, is too far-reaching and causing issues. Changing it to a less strict one may resolve persisting issues without requiring you to remove the firewall rule entirely.

How to Fix Cloudflare Error 1020 as a Visitor

Since you don’t have access to the admin panel, your options are less effective. However, there are still plenty of ways to implement a Cloudflare Access Denied bypass. You could always contact the administrator and ask to resolve your error code 1020 issue. That’s usually unlikely to happen, though.

Verify That Other Pages on the Website Are Working

Before attempting any other error code 1020 fix, you should first verify that other pages on the website work. In cases where it’s a single page, you’re likely attempting to access a forbidden document, so it’s showing the error 1020. Website-wide errors are likely due to a bad configuration or having your IP address banned. It could also be due to VPN use.

Check if VPN Use Is Causing the Error 1020 ‘Access Denied’

Some websites opt to disallow popular, commercially available VPNs. Since the number of IP addresses provided, compared to residential proxies is relatively small and often well-known, access may be restricted by default.

Turning off your VPN may let you bypass Cloudflare’s error 1020 by simply accessing the website from a non-restricted IP address. If, however, you still need to change your IP address and your VPN is banned, residential proxies are the preferred option.

Switch Your IP Address With Residential Proxies

Similarly to the VPN case, your residential proxy IP address may be blocked by the website, causing the Error 1020 Access Denied. Simply switching IP addresses (with sticky proxies) could resolve the problem.

If you’re getting the same Cloudflare 1020 error with rotating proxies, however, then that’s an indication that either the error is affecting the entire website (which is unlikely) or that it’s detecting your proxy, scraper, or any other solution.

Rotate and Utilize Browser-Like User Agents

If you’re using some sort of software, such as a headless browser, to connect to the website, you may be getting the Error 1020 Access Denied due to the software being detected. Most websites will attempt to deny automated access (such as bots) to their content, throwing out an Access Denied error.

While there’s no silver bullet in these cases, a common fix is to find user agents and other HTTP headers that will make your software look like a regular browser. Assuming you’re already using proxies, rotating IP addresses and user agents should greatly reduce the likelihood of getting that error.

Use a Different Access Method

Finally, if nothing else helps, sometimes using a different connection method through software may be a solution. For example, if you’re using the Python requests library, switching to Selenium and a headless browser may be a good solution.

Final Thoughts

Error 1020 is just another way to restrict users from accessing a website. While encountering it can be frustrating, you can fix it fairly easily. Trying the suggested tips should help you fix it and get back to surfing in no time.
