Error 521 Ray Web server is down when accessing through a domain. But I can access my website using IP address.

The picture showed Cloudflare cannot connect to HOST.
So, that’s why I’m contacting Digital Ocean because I use you guys to host (droplet). However, I do use Cloudflare for security purpose and I set up to point back to the IP address I got from Digital Ocean.
Please help me. Thank you so much.
