Ohme charger shows E14; app may indicate 'OCPP server error' or 'Backend communication fault'.

Note: Charging may still function in basic mode even if cloud communication fails.

• 1. Check Ohme service status: Consult Ohme support channels or website for any reported outages.
• 2. Verify internet access: Ensure your home internet is working by testing from another device on the same network.
• 3. Router settings: Make sure your router is not blocking outbound connections from the charger (no strict firewall rules or parental controls affecting the device).
• 4. Power-cycle charger and router: Restart both devices and allow several minutes for reconnection.
• 5. Local-only operation: If E14 persists but you need to charge, use manual or basic scheduling modes that do not rely on live cloud communication (if supported).
• 6. Contact support: Provide Ohme support with the error code, charger serial number, and network details. They may push a configuration or firmware fix remotely.
