Blink red three times before connected to cloud

Firmware

When I trying to connect my device to cloud It blink red three times,
What’s the meaning of the red blink?
1.blink blue
2.blink cyan
3.blink red three times
4.breath cyan

Blink red three times after blinking cyan is a connection failure making the cloud connection. It will retry, so if you then got to breathing cyan it worked on a subsequent try.
