How can I set up free SSL certificate offered from cloudflare?

I recently signed up for free SSL certificate provided by cloudflare.Within short period of time it is activated but it showing error “521(web server is down)” or “site refuse to connect”.I tried to get solution for that but no concrete solution found.Is anybody know how to set up free cloudflare SSL certificate for my site with digital ocean droplet?


I’m having this same issue, does anyone know why we’re receiving 521s?

  • pointed dns to cloudflare
  • pointed cloudflare to DigitalOcean IP -waited 48 hours
