Hi there! I understand your FoxCloud 2.0 app is showing offline, and I’d love to help you get it back online. To get started, could you tell me a bit more about your situation? For example, has anything changed recently with your home network, like a new Wi-Fi router, a changed password, or did you update the router’s settings (like switching Wi-Fi bands)? Also, is the inverter or device itself still displaying normal activity when the app says offline?

These details really help narrow down the cause. Typically, the most common reason for the FoxCloud app going offline is changes to your home network since the Fox ESS WiFi dongle only supports 2.4GHz networks, so if your router was changed or upgraded and is now using 5GHz only, that could disconnect the device from the cloud1.

If you haven't checked this yet, here’s a step-by-step approach to troubleshoot:

1. Confirm your Wi-Fi router is broadcasting a 2.4GHz network because the Fox ESS WiFi dongle won't connect to 5GHz only.
2. Ensure that the Wi-Fi password hasn’t been changed. If it has, the system needs to be reconnected with the new password.
3. Restart both your Wi-Fi router and the inverter system to refresh their connections.
4. On your FoxCloud 2.0 app, try to manually refresh or reconnect to the device.
5. If these don’t help, re-pair your inverter with your Wi-Fi network by following the procedure (this might be detailed in your system manual or the official FoxEss support pages).

If you’d like, I can guide you through the reconnection process next. Let me know what you observe and what you’ve already tried!
