WD DL4100 start problem, no working (video)

Hi,
I need a help with my MY CLOUD DL4100. I noticed something like that yesterday morning (15.03.2020)
(this is my movie):


When I turn it on, nothing happens. After 2-3 minutes MY CLOUD turns off. After a few seconds it turns on again.
And again nothing happens.
I checked drives and everything is fine.

What can I do? What is going on?

At 3am everything was fine. When I got up at 7am it was not working anymore.

Please, can anyone help me?

Regards,
Przemek
