The error messages that start with 1xxx refer to connectionproblems on sites that use the Cloudflare proxy. One of them is the Error 1020
Access Denied. This indicates that you’ve violated a firewall rule and your
request is blocked.
Before going into detail about what the error 1020 means,let’s talk briefly about using CDNs. They are a resource used to improve the
performance of access to the website.
In practice, there are copies of the website’s files spreadover the various servers that are part of the CDN. Thus, the user will be
connected to the server that is closest to their location.
Besides increasing performance, Cloudflare also offers somesecurity features that help protect the website from cyber attacks. Among them,
the DDoS attack, when several simultaneous accesses to the page occur, either
by real users or by so-called zombie computers.
