It might be a local routing problem that will soon be resolved, but if this has been going on for a long time then perhaps nobody has noticed.
You could write to the owners of this website and ask if they'd be willing to let you access their origin URL directly. I think many would refuse but it might be worth trying your luck.
Aside from that I'm not really sure what you could do. Perhaps mention what country/city you're in and your ISP and see if local HN users can replicate your results.
Ping or mtr 104.17.92.24. Any loss? Route seems to be correct? I.e. doesn't look like it's being proxied with your ISP etc.
Does a regular HTTP request work? curl -v http://cloudflare.com If that replies wanting to redirect you to the HTTPS site I'd guess you are looking at either a problem with libressl or certs on your system.
You might also be coming from an IP or network that Cloudflare has simply blocked.
