The charger shows E27 and will not charge; the app may indicate 'OCPP server error' or 'backend communication fault' on networked units.

Safety: Network issues do not affect electrical safety, but some installations require backend connectivity to authorize charging.

• Step 1 – Check Local Network: Verify that your router and internet connection are working. Test with another device on the same network.
• Step 2 – Wi‑Fi/Ethernet Status: In the Enel X app, check the charger’s network status. Re‑enter Wi‑Fi credentials or check Ethernet cabling as needed.
• Step 3 – OCPP Settings: For managed installations, confirm the OCPP server URL, port, and credentials with your service provider.
• Step 4 – Reboot and Retry: Power cycle the charger and router, then check if E27 clears.
• Resolution: If the local network is fine but E27 persists, the communication module may be faulty or the backend server may be down; contact Enel X or your operator.
