What should i do to fixed?

Hi,

Regarding your problem, please try to scan the code to re-configure the network or manually add the device to configure the network. If an exception occurs during the configuration process, you need to provide a complete network configuration screen recording.
(If the above operation does not work, please try to send the fault to: support.na@dreame.tech)

We hope the above information is helpful to you.
