+### 🛡️ Reverse Proxy / `trusted_proxies` Setup (Optional)
+
+#### 📘 Step-by-Step Instructions
+
+1. Open your `configuration.yaml` file (usually located in `/config`).
+2. Add or update the `http:` section to include `use_x_forwarded_for` and `trusted_proxies`:
+
+```yaml
+http:
+  use_x_forwarded_for: true
+  trusted_proxies:
+    - 172.30.33.0/24  # Default range for Home Assistant add-ons
+    - 127.0.0.1       # Localhost (if relevant)
+    - 192.168.1.100   # Example: IP of your reverse proxy or VM host
+```
+
+🔎 How to Find Your Add-on or Proxy IP
+
+If you're unsure of the IP range your add-on or reverse proxy uses, you can inspect the Docker network:
+```bash
+docker network inspect hassio
+```
+
+Look under the "Containers" section to find the IP of your Newt add-on or proxy.
+✅ When to Use This
+
+You need this setup if:
+
+    You're using a reverse proxy (e.g., NGINX, Traefik).
+
+    Your add-on or proxy accesses Home Assistant via internal IP (e.g., 172.30.x.x).
+
+    You're seeing token errors or "403: Forbidden" in the logs.
+
+🔄 Final Step
+
+After editing configuration.yaml, restart Home Assistant for the changes to take effect:
+
+    Go to Settings → System → Restart
+    or
+
+    Run via CLI:
+    
+```sh
+ha core restart
+```
