Clover Flex Connection Failure Diagnostic Report - Solar... | terminalfaults.org

Technical Background:

Clover Flex communicates using TCP/IP protocol. Connection failures can stem from several areas: 1) Power fluctuations during/after the outage causing internal voltage rail instability. 2) Corrupted network configuration within the Flex. 3) DNS resolution issues. 4) Firewall or port blocking. 5) Signal attenuation due to cable damage. 6) Expired SSL certificates.

Symptoms:

Device unable to connect to Scotiabank server. Connectivity failure occurred after a reported Telus internet service interruption.

Possible Causes:

Network configuration corruption within the Clover Flex device.
DNS resolution failure preventing the device from locating the server.
Firewall or port restrictions blocking communication with Scotiabank's server.
Telus internet service outage caused a disruption that the Flex did not recover from.
Cable strain or damage on the network connection.
Expired or invalid SSL/TLS certificates.

Solution:

1

Perform a hard reboot of the Clover Flex by holding the power button for 10 seconds until the device restarts.
2

Verify network connectivity by checking the Wi-Fi or Ethernet connection status on the device.
3

Check and reset the network settings on the Clover Flex. Ensure the device is configured to obtain an IP address automatically (DHCP).
4

Test the internet connection by pinging a public server (e.g., 8.8.8.8) via the Clover Flex's diagnostic tools (if available).
5

Verify the DNS server settings on the Clover Flex or the local network. Use a reliable public DNS server (e.g., 8.8.8.8 or 1.1.1.1).
6

Power cycle the Telus modem and router. Unplug both devices for 60 seconds, then plug the modem back in and wait for it to connect before plugging the router back in.
7

If using Wi-Fi, ensure the Clover Flex is within range of the Wi-Fi router and that there are no obstructions causing signal interference.

Safety Warning:

Safe Handling: Unplug the Clover Flex from the power source before performing any maintenance. Static electricity can damage electronic components. Discharge static electricity before touching the device by touching a grounded metal object. Do NOT attempt to open the Clover Flex device casing.

Prevention:

Implement the following:
• Regular cleaning of the Clover Flex's touchscreen with a dry, anti-static cloth.
• Ensure Ethernet cables are properly secured to prevent strain and damage.
• Position the Clover Flex away from sources of electromagnetic interference (EMI).

Expert Tip:

If the Clover Flex uses a static IP address, verify that the gateway and subnet mask are correctly configured. Incorrect network settings are a common cause of connectivity issues after an internet outage. An external USB ethernet adapter can isolate between internal NIC/OS issues from the physical connection.

Frequently Asked Questions

•What is the IP address assigned to the Clover Flex?

Check the Clover Flex network settings to determine its IP address. Compare to expected range if using Static IP.

•What is the signal strength of the Wi-Fi connection (if applicable)?

Check the Wi-Fi settings on the Clover Flex to determine the signal strength. Low signal strength can cause intermittent connectivity issues.

•Are there any error messages displayed on the Clover Flex screen?

Note any error messages. These may provide clues to the cause of the connection failure.
