Getting a 524 Error - What's Causing It and How Can I Fix It? or Why Am I Seeing a 524 Error and How

Bro, same. Mine was a DNS propagation issue after migrating hosts.

Used https://www.whatsmydns.net/ to check if everything resolved properly. If your nameservers are flaky, Cloudflare throws a 524.

Might wanna double-check your DNS settings in Cloudflare too.
