It sounds like the Core2 isn’t maintaining a stable connection with UIFlow. A few things to try:

1. Reflash the firmware with the latest stable UIFlow_Core2 version using M5Burner, and ensure "Internet Mode" is selected. 2. Double-check that the Device Name/API Key in UIFlow matches what's shown on the Core2 screen. 3. Disable any firewalls or antivirus that might block the connection. 4. Try using UIFlow Desktop IDE instead of the web version for better stability. If issues persist, test on another PC to rule out local system conflicts.

@kc5jim Hi there, now it can access,can be the regional differences in reasons.
