My Cloud EX2 Blue Flashing Light

So. I got the blue flashing lights. I just updated recently to 2.12.127…Then I could not access my nas. After doing some research I found that it may be due to a system checking.
Just to be clear my unit worked after unplugging and plugging again. But it appears that when going into hibernation, or out of it, it gets stuck. Blue flashing light. I let that thing sit for more than 4 days, and it was fixed…2 days later same thing. Any clue?
I am doing right now a backup on an external hd. Any suggestions with this issue?
Thanks
