Hello,
I am using AWS Lightsail to host my website. Using Cloudflare DNS + WAF for protection.
I am trying to whitelist the Cloudflare IPs on the AWS infra but after defining the ACL, the site becomes unreachable.
When i remove the ACL, site is back online.
I am making firewall rules for http and https.
Am i missing anything?
