Altice DVR fails too often.

Yesterday neither of two boxes would play or record. Play of recorded stuff would also not play using the Altice app on my phone. The streaming DVR function was completely non functional.

I powered off then on the main box but that did not fix the problem. I sent the image below with a message to Altice support. Only received recognition auto reply.

Then a couple of hours later, streaming DVR was working. Like magic.
