Error 1020, What is it and How to Fix It? | A Complete Guide

Error Code 1020 typically occurs when trying to access a website protected by Cloudflare Out Link, a popular content delivery network (CDN) and security provider. This error indicates that Cloudflare’s firewall rules have blocked your access to the site due to security policies set by the website owner. Essentially, it means that your request violated a firewall rule, preventing you from reaching the website.

In this guide, we will explain what Error 1020 means, the causes of this error, and how you can fix it.

What is Error Code 1020?

Error Code 1020 is an HTTP status code that appears when Cloudflare’s firewall detects that a request from your browser is suspicious or violates the website’s security policies. Cloudflare automatically blocks this request to prevent potential security threats.

The typical message you see on the screen is:

“Access Denied: Error 1020 – This website is using a security service to protect itself from online attacks.”

This block can occur if the firewall detects malicious behavior, but it can also happen due to more innocuous reasons such as IP blacklisting or unusual activity patterns.

Causes of Error Code 1020

Understanding the root cause is essential for fixing Error Code 1020. Here are some common reasons why you might encounter this error:

  1. Violation of Website’s Firewall Rules: Cloudflare has strict security policies in place. Your request might have triggered one of the rules set by the website’s administrator.
  2. Blocked IP Address: Your IP may be blacklisted due to previous suspicious activity, or you could be using a VPN or proxy that has a bad reputation.
  3. Bot Detection: If Cloudflare suspects your request to be coming from a bot or automated system, it can block access, resulting in Error 1020.
  4. VPN or Proxy Use: Using a VPN or proxy server can sometimes lead to being flagged by Cloudflare if the VPN’s IP is associated with malicious activity.
  5. Unusual Behavior: Rapid refreshes, multiple simultaneous requests, or other patterns that might be interpreted as an attack can lead to a firewall block.

How to Fix Error Code 1020?

If you are facing Error Code 1020, follow these solutions to troubleshoot the issue:

1. Disable VPN or Proxy

If you’re using a VPN or proxy, try turning it off and accessing the website again. Cloudflare may have flagged your VPN’s IP address, and by using your normal network connection, you can bypass the block.

2. Clear Browser Cache and Cookies

Sometimes, corrupt or outdated cookies and cache can trigger a firewall block. Clearing your browser’s cache and cookies might help in resolving the issue.

Steps to Clear Cache and Cookies:

  • In Chrome: Go to Settings > Privacy and Security > Clear Browsing Data.
  • In Firefox: Go to Options > Privacy & Security > Cookies and Site Data > Clear Data.

3. Use a Different Network

Switching to a different Wi-Fi network or mobile data connection can help. If your IP address is blacklisted, this change will assign a new IP, potentially allowing access to the site.

4. Contact the Website Administrator

If the issue persists and you believe you are wrongly blocked, reaching out to the website’s admin is the best solution. They can whitelist your IP or adjust firewall settings on their Cloudflare dashboard to resolve the problem.

5. Check for Bot-Like Activity

Ensure that no browser extensions or background apps are making automated requests to the website. Disable any suspicious extensions and avoid refreshing the page too quickly to avoid triggering Cloudflare’s bot protection.

For Website Owners: How to Fix Error Code 1020 on Your Site

If users are reporting Error Code 1020 on your site, it may indicate that your firewall rules are too strict. Here’s how you can resolve the issue as a website owner:

  1. Review Firewall Rules: Check your Cloudflare dashboard to ensure that your firewall settings aren’t overly aggressive. Loosening specific rules might solve the problem for genuine users.
  2. Whitelist Trusted IPs: If certain users are being wrongly blocked, you can manually whitelist their IP addresses to allow them to access your site without restrictions.
  3. Monitor Security Logs: Cloudflare’s analytics and logs can provide insight into why a particular IP was blocked. Use these to fine-tune your security settings.
  4. Disable Bot Protection for Specific Pages: If your page doesn’t need high-level security, consider reducing bot protection or adjusting the settings for certain parts of your site.

Conclusion

Error Code 1020 is a Cloudflare security measure designed to protect websites from potential threats. For end-users, solutions like disabling VPNs, clearing cache, and switching networks can often resolve the issue. Website owners, on the other hand, should review and adjust firewall settings to ensure legitimate users aren’t unintentionally blocked.

By following the troubleshooting steps mentioned above, you should be able to resolve the issue quickly. If all else fails, contacting the website’s support team is always a solid backup.
