Impark Reef App: Troubleshooting Network Unavailable... | terminalfaults.org

Technical Background:

The Reef app relies on secure TLS/SSL communication with Impark's servers for API calls. A 'Network Unavailable' error suggests a failure in establishing this secure connection. This can stem from issues with DNS resolution, cached TLS certificates, or incorrect API response handling. The app's ability to correctly parse JSON responses from the API is also crucial. Erratic kiosk power fluctuations can also corrupt the OS-level DNS resolver cache.

Symptoms:

The Impark Reef app displays a 'Network Unavailable' error despite a reported strong Wi-Fi signal at the kiosk location.

Possible Causes:

Incorrect TLS/SSL configuration on the kiosk or server-side, leading to handshake failures.
DNS resolution failure, preventing the app from locating Impark's servers.
Firewall restrictions blocking outgoing traffic on necessary ports (443 for HTTPS).
Expired or invalid TLS certificate cached by the Reef app or the operating system.
API server-side issues resulting in HTTP error codes (5xx) or malformed JSON responses.
Software bugs within the Reef app that do not gracefully handle network interruptions or API errors.

Solution:

1

Verify the kiosk's date and time settings are accurate. Incorrect time can cause TLS/SSL certificate validation failures.
2

Clear the Reef app's cache and data through the kiosk's operating system settings. This will remove any potentially corrupted cached certificates.
3

Flush the kiosk's DNS cache using operating system commands (if accessible).
4

Check the kiosk's network settings to ensure it is configured to automatically obtain DNS server addresses. Alternatively, configure public DNS servers like 8.8.8.8 and 8.8.4.4.
5

Confirm that the kiosk's firewall (if present) allows outbound traffic on port 443 for HTTPS.
6

If possible, examine the Reef app's logs for specific error messages related to TLS/SSL or API communication. Report these logs to Impark support.
7

Restart the Reef App and, if the problem persists, reboot the entire kiosk system.

Safety Warning:

Exercise caution when interacting with the kiosk's software. Avoid unauthorized modifications to system settings. Ensure hands are dry when interacting with the kiosk's touchscreen and buttons to prevent electrical hazards. Do not attempt to force or manipulate any buttons or panels on the kiosk.

Prevention:

Regularly update the kiosk's operating system and the Reef app to the latest versions. Monitor network connectivity and application logs for any recurring errors. Implement a centralized kiosk management system for remote monitoring and updates.

Expert Tip:

Some kiosks have a hidden 'debug' menu accessible via a specific key combination or tap sequence. This menu may provide access to network diagnostics and application logs. Document all changes made during troubleshooting to facilitate rollback if necessary.

Frequently Asked Questions

•What specific API endpoint is the Reef app attempting to reach when the error occurs?

This information can help narrow down the server-side issue.

•Does the kiosk have any other network-dependent applications that are also experiencing connectivity issues?

This can determine whether the problem is specific to the Reef app or a broader network issue.

•What version of the Reef app is installed on the kiosk?

Knowing the version can help determine if there are known bugs or compatibility issues.
