  encode gzip
  root * /srv/www/endershollow
  file_server
  try_files {path} {path}/ /index.html
}

Common Errors & Fixes

• Port 80 in use → nginx still running:
  sudo systemctl disable --now nginx
• ACME DNS 400 (no valid A records) → DNS not pointing to VPS:
  Create A records for endershollow.com, docs, noco → VPS IP.
• Unrecognized directive: rate_limit → not in Caddy core; remove it or use a plugin.
• Validate config: sudo caddy validate --config /etc/caddy/Caddyfile.
