Alternative Methods

# === Caddy & Self-signed & Cloudflare ===

# Method 2: Caddy (Easiest)
# sudo apt install caddy
# sudo nano /etc/caddy/Caddyfile
#
# comfyui.example.com {
#     reverse_proxy localhost:8188
# }
#
# sudo systemctl restart caddy
# Done! Caddy auto-gets Let's Encrypt certificate

# Method 3: Self-signed Certificate
# openssl req -x509 -nodes -days 365 -newkey rsa:2048 \
#     -keyout /etc/ssl/private/comfyui.key \
#     -out /etc/ssl/certs/comfyui.crt \
#     -subj "/CN=comfyui.local"

# Method 4: Cloudflare Tunnel
# curl -L https://github.com/cloudflare/cloudflared/releases/latest/download/cloudflared-linux-amd64 -o cloudflared
# chmod +x cloudflared
# ./cloudflared tunnel login
# ./cloudflared tunnel create comfyui
# ./cloudflared tunnel route dns comfyui comfyui.example.com
# ./cloudflared tunnel run --url http://localhost:8188 comfyui
