+# PostgreSQL Connection Fix
+
+## Problem
+App was trying to connect to PostgreSQL before it was ready, causing ECONNREFUSED errors.
+
+## Solution
+Modified docker-compose.yml to use proper depends_on with condition:
+
+```yaml
+depends_on:
+  traefik:
+    condition: service_started
+  postgres:
+    condition: service_healthy
+```
+
+This ensures the app waits for PostgreSQL healthcheck to pass before starting.
+
+## Status
+Fixed - ready for production deployment test.
