Troubleshooting Worldline Bambora 502 errors related to proxy server settings. Focus on network connectivity and configuration, adhering to PCI-PTS security.
Check the terminal's network configuration menu or consult the network administrator.
Investigate other devices to isolate the problem to the terminal or the network.
Check with the network administrator about recent server changes.
A 502 error signifies that the terminal, acting as a client, successfully contacted the configured proxy server, but the proxy server received an invalid or unavailable response from the upstream server. This often stems from network misconfiguration, DNS resolution issues, or server-side problems. The Bambora terminal's communication relies on secure TLS/SSL channels, verified network configurations and proxy settings are essential. Voltage stability at the terminal's power supply is also critical for reliable network operation.
Safe Handling: Always unplug the terminal from the power source before performing any physical inspection or cleaning. Avoid using excessive force when connecting or disconnecting cables. The Worldline Bambora terminal is a PCI-PTS certified device. Do NOT attempt to open the device casing or tamper with its internal components. Doing so will trigger anti-tamper mechanisms, rendering the device permanently inoperable and voiding any warranty.
Maintain accurate records of network configurations, including proxy server settings. Implement change management procedures to ensure that any modifications to the network or proxy server are properly documented and tested. Regularly monitor the terminal's network connectivity and performance. Clean the touchscreen with an approved cleaning wipe to ensure proper input. Ensure the terminal power cable is free from strain and securely connected.
Before modifying proxy settings, document the current configuration. If the terminal supports it, check the network logs for clues related to the 502 error. Consider using a DHCP reservation for the terminal's IP address to prevent IP address conflicts. Check for any firmware updates available for the Worldline Bambora terminal. Outdated firmware can sometimes cause network communication problems.
