521 = Web server is down

HTTP response status code 521 Web server is down is an unofficial server error that is specific to Cloudflare. This HTTP status code occurs when the HTTP client was able to successfully connect to Cloudflare but it was unable to connect to the server.

My advice: Try again later.
