Diagnostic steps for Bambora payment terminal displaying 502 errors specifically when connected via Telus internet. Focus: external network and hardware.
This determines which physical connection to inspect first.
Helps isolate whether the problem is specific to the terminal or a broader network issue.
Checks for possible cable or hardware damage.
502 errors indicate a 'Bad Gateway' response from a server. This suggests a communication breakdown between the payment terminal and the Bambora payment gateway. Network connectivity issues, DNS resolution failures, or firewall restrictions on the Telus network could be contributing factors. The Telus network might be experiencing temporary packet loss or latency that exceeds the terminal's timeout threshold. EMV/NFC transactions rely on stable voltage and baud rates; network errors can interrupt these processes. ESD can corrupt packets in transit.
Avoid contact with water or liquids near the terminal and power outlets. Ensure adequate ventilation around the terminal to prevent overheating. Do NOT attempt to open or modify the terminal, as this will void the warranty and potentially trigger anti-tamper mechanisms. Unplug the device during cleaning.
Implement cable strain relief measures to prevent damage to the Ethernet cable. Regularly clean the terminal's exterior with a dry, anti-static cloth to prevent dust buildup and potential ESD issues. Ensure the terminal is placed in a location with adequate ventilation to prevent overheating. Minimize cable bends close to the connector.
If the issue persists, try configuring the Bambora terminal to use a static IP address instead of DHCP. This can sometimes improve network stability and resolve DNS resolution issues. Document the changes prior to implementation to allow for easy rollback in the event of failure. Ensure the static IP is outside the DHCP range and does not conflict with any other devices on the network.
