I had the problem. I did the system restore. And at least the full factors restart (what is maybe a good thing to do right away)
After that my Cloud was going to sleep mode, but after the first upload not more. Than i went to the dashboard, to try to turn off any “constant connections” that may hold my cloud turned on.
I went to Settings > General and there is under Language and clock the option “NTP Service” (i´ve turned it off) and under Cloud Access the option “Cloud Service”
After i turned off these two thing my cloud was going to stand by mode. But i wanted to know what of these two is the problem. I turned on the NTP Service (because i think that a Clock Service would not make such a big issue, and i saw much people talking about this for years and WD dos not give an answer)
After that my cloud was still going to sleep, i turned the Cloud Service on and it was not going to sleep. Now it´s turned off.
I don´t know if this is a problem that this option is turned off, but the cloud is now making his job.
PS: BE PATIENT IT TAKES TIME
