-## 🔧 Resolving "No Available Server" in Coolify
+## 🛑 Resolving "Bind for 0.0.0.0:3000 failed: port is already allocated"
 
-If Coolify displays **"No available server"** or Traefik returns a **503 / 502 error**, follow these exact fixes:
+### Cause of the Error
+When deploying in Coolify or a multi-container Docker host, port `3000` on the host machine is frequently already taken by Coolify's internal service, another app, or a reverse proxy. Explicitly binding host port `3000:3000` causes Docker daemon to crash with:
+`Error response from daemon: Bind for 0.0.0.0:3000 failed: port is already allocated`
 
-### 1. Fix Health Check Path & IPv4 Resolution (Included in codebase)
-- **Cause**: Alpine Linux `wget` resolves `localhost` to IPv6 (`::1`), while Node Express binds to IPv4 (`0.0.0.0`). When `wget` fails, Docker marks the container `unhealthy`, causing Coolify Traefik to drop the container.
-- **Fix**: The updated `Dockerfile` and `docker-compose.yml` use native Node.js HTTP checks against `http://127.0.0.1:3000/api/health`:
-  ```bash
-  node -e "require('http').get('http://127.0.0.1:3000/api/health', (r) => process.exit(r.statusCode === 200 ? 0 : 1))"
-  ```
-- **Coolify UI Setting**: Under your resource in Coolify -> **Health Check**:
-  - **Path**: `/api/health`
-  - **Port**: `3000`
+### How It Is Fixed in This Repository
+In `docker-compose.yml`, direct host port binding (`ports: - "3000:3000"`) has been replaced with container exposure (`expose: - "3000"`).
 
-### 2. Configure Exposed Port in Coolify UI
-- **In Coolify Dashboard**:
-  - Open your deployed application/stack.
-  - Go to **Settings** -> **Exposed Port** (or **Port**).
-  - Ensure the port is set to `3000`.
+Coolify's Traefik reverse proxy routes external web traffic directly into the container on port `3000` via Docker's internal container network. No host port allocation is required!
