Diagnosing a 'Service Unavailable' error on a Clover Flex terminal after data migration. Troubleshooting steps for retail environments.
Obtain from network settings.
Check Wi-Fi settings menu.
Investigate any network upgrades.
A "Service Unavailable" error indicates the terminal cannot establish a connection to the payment processing server. This may stem from network connectivity issues, incorrect server configuration, or corrupted application data. Voltage fluctuations, ESD, or data corruption during the migration process can also contribute.
Avoid using the Clover Flex near liquids or in high-humidity environments. Ensure adequate ventilation to prevent overheating. Do not attempt to open or modify the device, as this will void the warranty and may trigger anti-tamper mechanisms. If the device is overheating, safely unplug it and allow it to cool down.
Maintain stable network connectivity. Ensure the terminal has a dedicated power source to avoid voltage fluctuations. Regularly clean the touchscreen with a microfiber cloth and approved cleaning solution. Implement cable strain relief measures to prevent damage to the power and network cables.
Access the Clover Flex diagnostic menu (if available) to check network connectivity status, signal strength, and server reachability. A common fix after migrations is to fully reset the network adapter from the settings menu, not just rebooting the device.
