What causes Cloudflare error 1020 access denied?

In a recent support request that we received, the webmaster’s developer working from another country is unable to access the website. The error message on the screen was:

access denied

In general, WAF firewall rules blocking access to the website can trigger the above error message.

If you are receiving this error on any random site, it means the website owner has implemented a Firewall rule in Cloudflare. This rule is either blocking your IP address, browser, or country.

Likewise, if you receive this error for your own site, it can be fixed easily by proper identification and modification of the offending rule.

The first step is to confirm if the error is actually related to Cloudflare. Temporarily disabling it from the Cloudflare portal can confirm it.  The Pause Cloudflare on Site option under the Overview tab in the Cloudflare portal can stop Cloudflare temporarily.

At times, if the Firewall activity log may not provide a clue on the exact rule id. Hence, we then will need to go for a trial and error method. That is, we need to disable all the firewall rules and then enable them one by one. Just a click on the toggle switch next to the rule id will turn the rule ON/OFF.
