+# Database Credentials Issue - Troubleshooting
+
+## Problem
+Directus is trying to connect with user `sparkuser` but the database has user `bbdf554`.
+
+## Root Cause
+Coolify might have environment variables that override the docker-compose.yaml values.
+
+## Solution Options
+
+### Option 1: Check Coolify Environment Variables
+In Coolify UI → Application → Environment Variables:
+- Look for `DB_USER` variable
+- If it says `sparkuser`, delete it or change to `bbdf554`
+
+### Option 2: Add .env file to override
+Create a `.env` file in the repo with:
+```
+DB_USER=bbdf554
+DB_PASSWORD=Idk@2026lolhappyha232
+```
+
+### Option 3: Hardcode in docker-compose (already done)
+The docker-compose.yaml already has hardcoded values, but Coolify's `env_file: .env` might be overriding them.
+
+## Current Status
+- PostgreSQL: ✅ Running with user `bbdf554`
+- Redis: ✅ Running
+- Frontend: ✅ Running
+- Directus: ❌ Can't connect (wrong username)
+
+## Next Steps
+1. Check if Coolify has environment variable overrides
+2. Remove any `DB_USER=sparkuser` variables
+3. Redeploy
