Caddy + Cloudflare SSL on Proxmox — HTTPS for Everything (2026)
Set up Caddy as a reverse proxy on Proxmox with automatic HTTPS via Cloudflare DNS-01 challenges — no ports exposed to the internet. We build a custom Caddy binary with the Cloudflare DNS module using xcaddy, manage the binary properly with dpkg-divert, and proxy four services with valid Let's Encrypt certificates.
