What is Cloudflare 1020 and what does the error code signify

Cloudflare 1020 indicates a problem with the connection to the Cloudflare edge server. It typically means that there's an issue with the DNS resolution or the connection between your origin server and Cloudflare.

Troubleshooting involves checking your DNS settings, verifying your origin server's reachability, and contacting Cloudflare support if the problem persists.
