ABL charger’s communication with backend or app is unstable; sometimes online, sometimes offline, without a specific error code.

Steps:

• Check Wi‑Fi signal strength at the charger using a smartphone; if weak, consider relocating the router or using a Wi‑Fi extender.
• For Ethernet, replace the patch cable and ensure connectors click firmly into place.
• Assign a static IP to the charger to avoid DHCP conflicts, if supported.
• Ensure firewall rules allow outbound connections to the ABL backend or OCPP server ports.

If connectivity remains unstable with a known‑good network, the ABL communication module may be defective and require replacement.
