Somchai API

### Error Analysis for 'Somchai API' * **Root Cause:** The application failed to connect to its PostgreSQL database within the configured timeout period during startup. The library `psycopg` is a Python-to-PostgreSQL database adapter. * **Simple Explanation:** When the application started, it tried to talk to its database. The database didn't respond in time, so the connection attempt "timed out." Because the database is essential for the application to run, the application shut itself down. * **Areas to Investigate:** * **Database Availability:** Is the PostgreSQL database server running and healthy? * **Network Connectivity:** Check if the application container can reach the database server. Verify firewall rules, DNS, and network configuration between them. * **Connection Credentials:** Ensure the database hostname, port, username, and password in the application's configuration are correct. * **Database Load:** The database might be too busy to accept new connections. Check its CPU, memory, and active connection count. * **Severity:** CRITICAL. The application is completely down because it cannot start without a database connection.
