Charger displays E202; app shows 'Cloud communication error' or 'Cannot reach Enphase servers'.

Note: Charging usually continues locally; remote monitoring may be affected.

• Check internet: Verify that other internet services (web browsing, streaming) work from your home network.
• Router firewall: Ensure your router is not blocking outbound connections from the charger's IP. Disable overly strict firewall rules temporarily to test.
• Wait and retry: If Enphase has a known service outage, wait until status pages indicate recovery, then check the app again.
• Firmware update: When connectivity is restored, check in the app for any available firmware updates for the charger and apply them.
• If persistent only for charger: A technician may need to reset the communication module or replace it if it cannot maintain secure connections to the cloud.
