There’s an ongoing DNS propagation delay issue announced at https://www.cloudflarestatus.com/.
Currently, I can see only a few Asian DNS servers showing the NS records for your website, nothing else. Until the A, AAAA, CNAME etc are propagated, your website won’t work properly. Please see and monitor here: https://www.whatsmydns.net/#NS/chicagonature.com.
ps: A screenshot above reveals the IP address of your origin server. This is not recommended, and you should consider removing it, as one of the security benefits of Cloudflare is to obfuscate the origin, making it hard to hackers to attach your website directly, bypassing CF.
