Every day the Visitors in Realtime hangs

I brought this up before, but didn’t realize it happens every day. Every day at Midnight UTC (5 pm local time), the top part of the Visitors in Realtime report quits updating and the visitor list below it is empty. The link to the visitor log points to an empty page. Every morning it works fine again. Is there something going on in there at that time which would prevent it from working? It worked fine on 2.x, and quit working coincident with my first 3.x version install. I’m on 3.0.1 now. It doesn’t appear to lose any data, since the data from yesterday always appears to be caught up.

Thanks,
Dave

Thanks Dave, that’s seems a bug in Piwik 3 tracked here: Visitors in real time data gone after 4PM Piwik 3.0 · Issue #11165 · matomo-org/piwik · GitHub
