Control point MacOs 2021

[MiniMe]

I have v4.13.77 of Kazoo installed. I removed and reinstalled it previously.
To be sure disconnected and rebooted and or reset all my network items.
Also changed entire IP range to something else and set it back to the original range.
Pinged everything back and forth and checked all cabling also. Fast and reliable results.
I recall I thereafter MinimWatch had some problems finding MinimServer after this change of IP range. I fixed this via pointing MinimWatch to the current subnet via setting ohnet.subnet to x.x.x.0
From this I guess we can learn that MacOS somehow (assumed) creates a virtual subnet as soon as you go into another IP range or so, I did not change network adapters. But, this is still an assumption.
Regardless, Linn Kazoo when it works i.e. when it finds both ends of the scale, left = MinimServer , right = network player, there are no issues, also not after starting/restarting the computer.
So if network issue, I'd suspect either Mac itself with its magical subnet, or, the router itself could be the culprit (but if so I'd expect also other issues). Strangeness still happens, so I'll also keep testing to see if something is disturbing my network somewhere.
And in the meantime of all above, MinimServer keeps working and the app on my phone or tablet never have issues, nor does the network player.
