-no On / Off switch next to the Box
Problem: My box was already 2x not turn now. What helped both times, once briefly connect the box to a different outlet and then back to the old. Then it runs without any problems.
Since I've been playing a new update up, it did not happen again. Perhaps hing`s also due to.
