There is a new addon which has similar features but uses cloudflared so the domains are automaticly updated without cloaking which is a lot more comfortable. Pleas use cloudflared instead of this addon.

Ngrok & Freenom

This addon creates a Ngrok tunnel to your Home Assistant instance and forwards your Freenom domain to the tunnel endpoint so you don't have to worry about changing tunnel domains.

Configuration

1. Create a free account at ngrok and enter your authentication token to the add-on config.

2. Register a free domain at freenom and enter your username, password and domain name to the add-on config.

3. Lastly you can change the address of your Home Assistant instance if needed.

4. Ensure you have the following in your config.yaml:

   http:
   ip_ban_enabled: true
   login_attempts_threshold: 5
   use_x_forwarded_for: true
   trusted_proxies:
   - 127.0.0.1
   - ::1
   - 172.16.0.0/12

You're ready to go!
