Often Linn Kazoo cannot see MinimServer

[vilmos]

My setup:

MinimServer on Mac mini with macOS HighSierra (for reasons)

iMac with macOS Catalina running MinimWatch and sometimes also Kazoo.

Kazoo running on iPhone with iOS 14.4

My Router is Fritz!Box 7590, both Macs (and Linn DSM) connected via Ethernet, iPhone via WiFi

Symptoms:

After Mac mini is woken up from sleep, usually MinimServer is listed as Unavailable in Kazoo. Performing a Rescan on MinimServer usually makes MinimServer reappear in Kazoo. But not always, sometimes I have to Exit and Restart MinimServer.

Sometimes MinimServer also becomes Unavailable in Kazoo after I put the Linn DSM into sleep mode.

I often have the situation that MinimServer is Unavailable in Kazoo on the iPhone but available on the iMac or vice versa.

And usually MimimWatch takes 5 minutes or more before it no longer shows a dark grey background in the menu bar and becomes usable again.
