The problem of the device disappearing from the application after connecting to the WiFi network

The problem of the device disappearing from the application after the device is connected to the wifi, knowing that the device is in the blynk consol and it appears that it is online, I do not know why

Here the device is present before I connect it to WiFi

After I linked it it disappeared but it is in blynk consol
