Troubleshooting parking app errors reporting premature session expiry due to clock synchronization issues. Focus on API, TLS/SSL, and token management.
This helps determine if the problem is specific to the parking application or a system-wide issue.
Time zone discrepancies can cause clock synchronization problems.
Incorrectly configured NTP servers can lead to inaccurate system time.
The application relies on TLS/SSL for secure communication with the backend server. Incorrect system time can cause TLS/SSL handshake failures, leading to authentication problems. API responses are validated against a timestamp. Cached data, DNS resolution, and token validation are critical for session management. Latency exceeding acceptable thresholds can also trigger false positives.
The application displays a 'Parking Session Expired' message prematurely. This indicates a discrepancy between the application's internal clock and the server's clock, or an invalid token.
This kiosk is located in an unattended, public environment. Vandalism is a potential risk. Extreme temperatures (down to -40°C) can affect the device's performance. Ensure the device is securely mounted to prevent theft or damage. Safe Handling: Power down by normal software means. Do NOT disconnect power rapidly unless there is an emergency.
Implement robust error handling and logging within the application to capture clock synchronization errors. Regularly monitor the kiosk device's system time and NTP settings. Implement a mechanism for gracefully handling clock drift and token expiry discrepancies. Cache invalidation must be immediate.
Implement a 'time skew' tolerance within the application to allow for minor discrepancies between the client and server clocks. For example, allow a 60-second window of tolerance. Ensure the application logs the client and server timestamps when a 'session expired' error occurs for debugging purposes. Review JSON responses for parity across different API endpoints.
