Hi alll,
does by any chance s/o knows why I do have similar error messages every day? Date/Time shown format is German/MEZ:

I do have four WiFi cameras connected, but only m1 and m2 seem to have errors. I know them, I can ignore them but maybe s/o knows a solution?

That looks similar to when my cameras restart once a week. Are your cameras restarting?

[iconnor]

There is a log rotate that happens at midnight, wouldn't expect it to cause those errors though

Not that I would be aware of. The cameras have no Internet access (blocked in the router because they chat to much with obscure IP addresses), so I cannot imagine that they have a synchronized time and would restart midnight sharp.

Then it is down to basic troubleshooting.
I would start with pinging a working and troublesome camera just before midnight until the problem occurs to see if the camera remains on-line. This will show if it is ZM or not.
If the 2 test cameras use the same AP, this will show if it is the AP or the camera.

This simple test may isolate the problem.
