Zaptec charger reports E18; app message: ‘Network error / cloud connection failed’ and remote control is unavailable

Safety first: This fault does not affect electrical safety; local charging may still work.

Steps:

• Check local internet: Verify that your home internet connection is working on other devices.
• Wi-Fi signal: If using Wi-Fi, check signal strength near the charger. Consider moving the router or adding a Wi-Fi extender.
• Re-enter credentials: Use the Zaptec app to reconfigure Wi-Fi settings and ensure the correct SSID and password are used.
• 4G models: Check that the SIM (if used) is active and has coverage.
• Router settings: Ensure that outbound connections to Zaptec cloud servers are not blocked by firewall rules.
• If still offline: The communication module may be defective and require replacement.
