Control point MacOs 2021

[simoncn]

It is not unusual for a router to have problems with multicast discovery while working correctly in all other respects.

However, if you are using a UPnP control app on your phone or tablet without issues (is this also Linn Kazoo?), it seems the problem might be related to something on the Mac or the Mac version of Linn Kazoo.

When the server or player is missing from Kazoo on the Mac, does stopping and restarting Kazoo make the missing server or player appear? Does stopping and restarting the missing server or player make it appear? Either of these would suggest a UPnP discovery issue.
