DIAGNOSIS This is a server-side or app cache issue, often after a firmware update or if you've added too many devices to your account.
FIX Force close the Wyze app, clear its cache (in your phone's app settings), then reboot your phone. Try the setup process again on a strong cellular data connection, not Wi-Fi, to bypass any local network weirdness.
IF THAT DIDN'T WORK Log out of the Wyze app completely, delete and reinstall the app, then log back in. This flushes all corrupted local data.
HEADS UP This error is frustrating but almost never means your camera is bricked. It's an app/account glitch. Ensure your app is updated to the latest version.
