Mh I don’t get why at about 00:45 the raspberry stopped working, yesterday and today too about at the same hour. Yesterday I had to switch off the power physically and then on again. I can’t tonight but I really don’t understand why this happens. I don’t know what to look
@SonoMichele if you use DHCP, it may be that the IP leasing is expiring and not being renewed for some reason (that would explain the almost-periodical situation). I've seen this issue happen with some crappy cable routers (never on a Pi, though).
