Troubleshooting

If a SPARK is shown as offline in the ENLYZE App or cannot establish a connection during initial integration, the following page will help you quickly identify and resolve the issue.

By default, a SPARK’s network communication is restricted. A SPARK can communicate with other network participants if:

• They are in the same network as one of the SPARK’s network interfaces.

• They have access to the SPARK’s Internet (eth0) network via a gateway.

To access the SPARK from other networks, a manual route must be configured. Learn how to set up routes here.

Prerequisites Before Troubleshooting via ENLYZE EDGE

Please verify the following before starting the troubleshooting process:

• Is the SPARK powered on? → The SPARK is powered if a green LED on the front left is continuously lit.

• Is the Ethernet cable properly connected? → The Ethernet cable providing Internet access must be plugged into the SPARK port labelled “Internet.” ⚠️ No Internet uplink is possible via other ports on the SPARK.

• Is the other end of the Ethernet cable properly connected? → Check if the cable is connected to an active network port with Internet access (e.g., switch, router, or wall socket).

If all of the above conditions are met, you can begin the diagnostic process.

Diagnostics

Our diagnostics process helps you identify and resolve connection issues step by step.

Access ENLYZE EDGE and Start the Diagnostic Process

Access ENLYZE EDGE on the respective SPARK. If you need help, you can find the appropriate guide here. The connection test to the ENLYZE Manufacturing Data Platform will start automatically once you’ve successfully logged in and will show where the connection fails. You can run a new connection test at any time by clicking the “Test Connection” button.

The connection tests are sequential, ensuring that troubleshooting starts at the correct step. Fix the first displayed issue and run the test again to confirm the SPARK has reconnected to the ENLYZE Manufacturing Data Platform.

You may need to repeat the steps multiple times until the SPARK is back online.

Advanced Troubleshooting Process

Follow the steps in the process outlined below.

Firewall Settings Overview

Incorrect firewall settings are the most common cause of connection issues. Ensure the following rules are configured:

Host	Port	Protocol	Purpose
1.1.1.1	53 (DNS)	TCP and UDP	Hostname resolution
8.8.4.4	53 (DNS)	TCP and UDP	Hostname resolution
8.8.8.8	53 (DNS)	TCP and UDP	Hostname resolution
iot-edge-1.enlyze.com (159.69.177.150)	51821 (Wireguard)	UDP	Data transfer to ENLYZE Cloud, SPARK configuration, update deployment
ntp1.enlyze.com (157.90.230.207)	123 (NTP)	UDP	System time synchronization
ntp2.enlyze.com (162.55.43.234)	123 (NTP)	UDP	System time synchronization

SPARKs Must Be Exempt from UDP Flood Attack Protection

To ensure smooth communication, it is necessary to whitelist the SPARKs in the UDP Flood Protection module.
