Thank you for reporting this issue.

Analysis:

The error log shows a PostgreSQL password authentication failure:

PostgresError: password authentication failed for user \"postgres\"

This error originates from src/lib/migrate.ts:205 in the checkDatabaseConnection() function. The application is failing to connect to the database during startup, which causes the entire application to exit.

Root Cause:

The issue is related to Docker Compose environment variable configuration. When reinstalling cch with an existing database volume:

1. Database credentials mismatch: The DSN environment variable in your application container doesn't match the actual PostgreSQL credentials
2. Persistent volume: The old PostgreSQL data volume (data/postgres-dev) still exists with the previous database state

Potentially affected code:

• src/lib/migrate.ts:191-214 - Database connection check with retry logic
• src/instrumentation.ts:281-285 - Application exits if database connection fails
• dev/docker-compose.yaml:55 - DSN construction from environment variables

To help diagnose this, please provide:

1. Your .env file contents (remove sensitive values):

   • DB_USER
   • DB_PASSWORD
   • DB_NAME

2. How are you deploying? (Docker Compose / manual / other)

3. Check if there's a data volume from previous installation:

   ls -la data/postgres-dev/

Potential solution:

The DSN in your docker-compose is constructed as:

DSN: postgresql://${DB_USER:-postgres}:${DB_PASSWORD:-postgres}@postgres:5432/${DB_NAME:-claude_code_hub}

Make sure your environment variables match your actual database credentials. If you changed DB_PASSWORD after the first installation, the old PostgreSQL data volume will still have the old password.

To start fresh with new credentials:

# Remove old data volume
rm -rf data/postgres-dev

# Update .env with new credentials
echo "DB_PASSWORD=your-new-password" >> .env

# Restart
docker-compose up -d

Or if you want to keep existing data, ensure your .env file has the same password as the original installation.
