My MyCloud was inaccessable this morning, and when I looked at it the light was blinking yellow. According to the manual, that could mean either the network connection was out or there was a thermal problem. The ethernet cable was plugged in ok, and I have no reason to believe the temperature was out of range. I unplugged the power, waited 10 seconds, then plugged it back in and it came up blue in a few minutes and was accessable again and has been ever since. Could it have something to do with the leap second that was added last night?
I am still using firmware v04.00.00-607 because I’m afraid to upgrade until I get another drive to back-up the data on the MyCloud.
