Shopify POS Go: Domain Name Resolution Error... | terminalfaults.org

Technical Background:

Domain Name Resolution relies on the device's ability to query DNS (Domain Name System) servers to translate domain names into IP addresses. Failure can stem from incorrect network configuration, DNS server unavailability, firewall restrictions, or hardware issues affecting network connectivity. Signal attenuation from cable strain can interrupt network communication. Electrostatic Discharge (ESD) events, particularly prevalent in dry environments or during winter months, can temporarily disrupt or damage the network interface.

Symptoms:

The Shopify POS Go device fails to resolve domain names, preventing access to Shopify services and potentially other network resources. This manifests as errors during payment processing, inventory updates, or other online functions.

Possible Causes:

Incorrect network configuration on the POS Go device (e.g., wrong IP address, subnet mask, gateway, or DNS server settings).
Unreliable or unavailable DNS servers (either the configured DNS servers are down or experiencing issues).
Firewall restrictions blocking DNS traffic (port 53) or other necessary network communication on the local network.
Weak or unstable Wi-Fi signal strength or interference affecting network connectivity.
Cable strain or damage to the Ethernet cable (if applicable) affecting network signal integrity.
Temporary network outage or internet service provider (ISP) issues.

Solution:

1

Verify Network Connectivity: Ensure the POS Go device is connected to the network (Wi-Fi or Ethernet). Check Wi-Fi signal strength or Ethernet cable connection.
2

Check IP Configuration: Access the POS Go device's network settings and verify the IP address, subnet mask, gateway, and DNS server settings are configured correctly. Obtain these settings from the network administrator or router configuration.
3

Test DNS ReSolution: Use a network utility on a separate device on the same network (e.g., a laptop or smartphone) to ping a public DNS server (e.g., 8.8.8.8). If this fails, the issue is with the network itself, not the POS Go device.
4

Restart Network Equipment: Power cycle the router, modem, and any network switches. Wait for them to fully reboot before testing again.
5

Clear DNS Cache: If possible, clear the DNS cache on the POS Go device. Refer to the Shopify POS Go documentation for instructions. If not possible, a device restart may clear the cache.
6

Check Firewall Settings: Verify that the firewall on the network is not blocking DNS traffic (port 53) or other necessary communication for the POS Go device.
7

Contact Network Administrator: If the problem persists, contact the network administrator or IT support for further assistance in troubleshooting network connectivity and DNS resolution issues.

Safety Warning:

Avoid forceful manipulation of cables. Unplug the device from the power outlet before inspecting cables to avoid electrical shock. Ensure the area around the POS Go device is dry to prevent water damage. High levels of Electrostatic Discharge (ESD) can damage the device; ground yourself before touching it, especially in dry environments. Safe Handling: Unplug the POS Go device before moving or inspecting any cables.

Prevention:

Regularly check network cables for strain or damage, replace as needed.,Ensure stable Wi-Fi signal strength in the POS Go device's operating area.,Implement cable management to prevent strain on network cables.,Periodically verify the DNS server settings on the POS Go device and network router.,Keep the POS Go device and network equipment clean to prevent dust buildup and potential overheating.,Implement a UPS (Uninterruptible Power Supply) to prevent damage to the POS Go from power fluctuations.

Expert Tip:

If DNS resolution fails intermittently, consider using a public DNS server like Google's (8.8.8.8 and 8.8.4.4) or Cloudflare's (1.1.1.1) as the primary and secondary DNS servers in the network router configuration. This can sometimes provide more reliable DNS resolution than the default ISP-provided DNS servers. If Ethernet is being used, try a different known-good Ethernet cable to rule out cable defects.

Frequently Asked Questions

•What are the default network settings for the Shopify POS Go?

The default network settings depend on the network configuration. Typically, the POS Go device uses DHCP to obtain an IP address automatically. Consult the network administrator for specific settings.

•How do I check the Wi-Fi signal strength on the Shopify POS Go?

Access the network settings on the device. There should be an indicator showing the Wi-Fi signal strength. Refer to the Shopify POS Go documentation for specific instructions.

•Can a faulty power adapter cause DNS resolution issues?

A faulty power adapter is unlikely to directly cause DNS resolution issues. However, an unstable power supply can lead to unpredictable device behaviour, including network connectivity problems. Test with a known good power adapter as part of troubleshooting.
