Fixing Cloudflare Error Code 1020

Experiencing an Error Code 1020: Access Denied on your or your client’s website can be quite perplexing. This error signifies that access to the site has been blocked by Cloudflare’s security measures, specifically due to a violation of firewall rules. It’s crucial to understand the nuances behind this error to effectively resolve it and ensure uninterrupted access to your website.

Let’s dive into the root causes of this issue and explore both general and technical solutions for site visitors and administrators.

What’s causing the ‘error 1020: access denied’

At its core, Error 1020 Access Denied is triggered by Cloudflare’s protective measures over a website. Cloudflare acts as a shield, filtering incoming traffic to safeguard against malicious activities. When someone tries to access a part of the website that is deemed off-limits by the configured firewall rules, Cloudflare steps in, halting the access and displaying the error.

However, configurations that are too restrictive can mistakenly block legitimate users. It’s a delicate balance between security and accessibility, and sometimes, firewall rules need to be adjusted to accommodate legitimate traffic.

Resolving the issue that leads to the error code 1020 usually lies with the website administrator, but visitors can lend a hand, too.

For site visitors

If you stumble upon this error as a visitor, it indicates you’ve tried to reach a part of the website that, intentionally or not, has been restricted. The first step is to communicate with the site owner. Providing them with a screenshot of the error and the Cloudflare Ray ID, typically displayed at the bottom of the error page, can be incredibly helpful. This information aids the site owner in identifying and rectifying the issue.

If you’re encountering this error on your site without direct control over Cloudflare’s firewall settings, it suggests a configuration issue that might need a more technical approach to solve. Reaching out to support with detailed information, such as the error’s occurrence time and the Cloudflare Ray ID, can facilitate a quicker resolution. Describing the actions leading to the error also helps in diagnosing the problem accurately.

  1. Start by pinpointing the exact firewall rule that’s being triggered. This is essential for both understanding why legitimate requests might be getting blocked and for adjusting the rules accordingly.
  2. If a legitimate request is being blocked, consider tweaking the firewall settings. This might involve softening the rule that was violated or creating exceptions for certain IP addresses or URL paths.
  3. After making adjustments, it’s crucial to test and ensure that the issue is resolved without compromising the site’s security.
  4. If specific actions by visitors are leading to this error, consider adding more intuitive guidance on your site to prevent such incidents.
