Control can't see MinimServer after rescan until server Ethernet unplugged/replugged

The ohNet UPnP stack used by MinimServer is limited to using only one adapter per subnet. This means that if the Pi has a WiFi adapter and an Ethernet adapter active on the same subnet, MinimServer will broadcast UPnP announcements on one of these adapters and not the other. Depending on the network routing setup for your wired network and your wireless network, these announcements might be sent on an adapter that is not able to communicate with your control points and this might explain the problem.
