Cloudflare’s Proxy with Pterodactyl Panel

Go to DNS

Proxy Subdomain

Enable Cloudflare’s orange cloud proxy symbol for the panel subdomain

Proxy to Port 443

Visit https://dash.cloudflare.com/?to=/:account/:zone/ssl-tls and change the flexible SSL option to full. This proxies Cloudflare’s traffic to port 443 instead of port 80.

Create Origin SSL

Go to https://dash.cloudflare.com/?to=/:account/:zone/ssl-tls/origin and create an origin SSL for panel.example.com with a 15-year expiration date, then copy the public key into /etc/ssl/cert.pem and the private key into /etc/ssl/key.pem

Enable Origin Pulls

Go to https://dash.cloudflare.com/?to=/:account/:zone/ssl-tls/origin and enable the option “Authenticated Origin Pulls”
