Enphase › Enlighten / Enphase Cloud monitoring
Gateway stays reachable locally, cloud upload LED red
reported more than once
Symptoms
- Gateway shows a good Wi-Fi signal or is reachable on the local network (sometimes still reporting fine to a third-party tool like Home Assistant) but the cloud/upload LED stays red and the Enlighten app shows stale or no data for days to weeks
- WPS or AP-mode reconnection attempts fail
- Support cannot always tunnel in to fix it remotely. Enphase's own troubleshooting video covers the case where the reconnection cannot even start: after pressing the AP mode button the Envoy_ Wi-Fi network (last six digits of the serial) never appears in the phone's Wi-Fi list, or the AP LED does not turn green
