 # ✅ Coolify Deployment - FIXED!
 
-## What Was Wrong
+## Issues Fixed
+
+### Issue 1: Port Already Allocated ✅
 
 **Error:** `Bind for 0.0.0.0:8000 failed: port is already allocated`
 
-**Cause:** Your `docker-compose.yml` used `ports:` which tries to bind to the host's ports. Coolify uses Traefik reverse proxy, so it doesn't need (and conflicts with) port bindings.
+**Cause:** Your `docker-compose.yml` used `ports:` which tries to bind to the host's ports. Coolify's dashboard runs on port 8000, causing a conflict.
+
+**Fix:** Changed `ports:` to `expose:` - Coolify's Caddy reverse proxy handles routing
+
+### Issue 2: Module/File Not Found ✅
+
+**Backend Error:** `ModuleNotFoundError: No module named 'app'`
+
+**Frontend Error:** `npm error enoent Could not read package.json`
+
+**Cause:** Development volume mounts (`./backend:/app`, `./frontend:/app`) override Dockerfile COPY commands. In Coolify, these paths don't exist.
+
+**Fix:** Removed bind mounts from docker-compose.yml - files now copied by Dockerfile
