Error 521
Hello,
I just connected my AWS server to Clouflare. But I am getting the 521 Web server is down error.
I have configured the site so that Cloudflare ip's have access to inbound. The server itself is up, if I go to the public IP i can access it.
I also have the nameservers set to cloudflare, I don't believe I have a firewall set up
This is all I have done, thanks!

Make sure your Encryption mode(SSL/TLS -> Overview) is Full Strict or Strict SSL-only, so it's connecting over port 443
