What is Cloudflare Error 1020 Access Denied?

Cloudflare Error 1020 Access Denied happens when a firewall rule is violated on a site protected by Cloudflare. Corrupted browsing data and cache can lead to Error 1020 in Cloudflare. Therefore, it blocks the connection request that comes to that site.

Below we’ve suggested a few fixes to help you eliminate this error issue. Let’s learn about them in detail.

· Identify the Error

The first thing you need to do is to identify whether the error is Cloudflare related.

How to determine if the error is Cloudflare related?

  • Visit Cloudflare portal
  • Choose Overview
  • Allow Pause Cloudflare on Site.

Now follow the steps to find which rule is causing Error 1020 to happen.

  • Log in to the Cloudflare Dashboard
  • Sign in with the correct Cloudflare ID and password
  • Choose the appropriate domain
  • Select firewall > overview
  • Check out the Activity log

· Resolve Firewall Rule Violation Issue

Go to Cloudflare portal > choose the Firewall rule tab > identify a particular rule to edit > select the wrench icon and edit.

2. How to turn off firewall rules?

If any firewall rules you are looking for in the activity log are missing, you may disable all the rules. Simply toggle the switch to Off. Then, gradually enable the rules you think are not causing the error.

· Enable the Use of Cookies in Your Browser

As we already mentioned, Cloudflare uses some cookies to change particular security features on the sites. So they can control user’s access to the site. Also, it allows the Cloudflare CDN to deliver users a reliable user experience.

Cookies are great for a website as long as it doesn’t block specific users from accessing it. Most of the time, cookies block access because your browser is set not to allow the cookies.

This mostly happens when you use Mozilla Firefox and Google Chrome. In these two browsers, you’ll need to follow separate guides.

How to enable cookies on Google Chrome?

· Clear the Browser Cache

Whenever you browse a website, it stores several files on your computer. The next time you visit the site, it loads faster. Thus, tons of outdated files exist on your computer like cookies, script files, etc.

When the server stops throwing the error, it will locally store the copy of these errors. You may experience the Error 1020 Access Denied issue even after visiting the website.

In this case, you might need to clear the caches from your browser setting. Go to the browser settings > clear all your caches and cookies. Some browser allows clearing the caches selectively.

This is safe because by clearing out the caches, you won’t lose your saved IDs, passwords, and personal files. Instead, all the files will be reloaded and make them updated. Restart the browser to check if the issue still exists.

· Check if Any Browser Extensions or Add-on Are Blocking Cookies

Your browser will likely have several extensions installed, which might be blocking cookies. People use some extensions for private browsing. However, these extensions can prevent a site from opening.

So, you need to check if any extensions are installed in your browser. If you found any extensions, disable them one by one until the problem is solved. Some common extensions or add-ons block cookies on Google Chrome and Mozilla Firefox.

  • NoScript on Firefox
  • Privacy Badger on Chrome and Firefox
  • Disconnect on Chrome
  • uBlock Origin on Chrome and Firefox
  • Ghostery on Chrome and Firefox
  • Cookiebro on Firefox

If any of the above extensions you found on your browser, disable it for good.

How to disable extensions on Google Chrome?

Click on the Extension icon and tap on Manage Extensions.

Extension section

A list of installed extensions will appear in a new tab. Identify the extension that you doubt is causing the problem of Error 1020 with Cloudflare.

Sometimes Error 1020 happens because your computer fails to communicate with the server. Your computer may have the incorrect date and time. So make sure to correct the time and date. Browse the website again to see if it works.

· Check Your Local Server Configuration

Sometimes the problem can happen in the backend or maybe in the site configuration. If you are the site owner, you can troubleshoot this issue by checking the Firewall rule environment first.

To do so, log in to the Cloudflare dashboard site. You can check all the certificates from there. Also, you can check if your server is configured correctly. You can confirm if the firewall causes the issue by checking the rules.
