Getting 521 error
The 521 is from your origin server and it’s either down or port 443 is not open.
Some questions, was the site working before? If so, what changed? If not, is it newly setup?
Some quick fix ideas to investigate here, Community Tip - Fixing Error 521: Web server is down.

When I have created the new droplet on digital ocean. and migrated the data to the new server IP ADDRESS was working fine which means when I hit enter the newly installed server’s IP address it working fine but new domain jobs.edufever.com is not pointing to origin server with the help of Cloudflare.
