- Eventually, the connection to MinimServer will appear
- It is always slow and other devices, like my streamer, are picked up faster. MinimServer is last

When Kazoo starts, it sends a UPnP M-SEARCH multicast message and other UPnP devices should respond immediately. Also, each UPnP device sends a UPnP NOTIFY multicast message to all other UPnP devices from time to time.

From your description, it sounds like NOTIFY messages are getting through but M-SEARCH messages (or responses to these messages) are not getting through. The ohNet UPnP stack used by MinimServer sends NOTIFY messages a bit less frequently than some other devices, which explains why MinimServer shows up last. MinimServer would show up immediately if M-SEARCH requests and responses are working correctly because MinimServer would send an immediate M-SEARCH response back to Kazoo.

Is there a way to increase the frequency of NOTIFY? It could be a workaround? Is there a way we can check this? With Wirehark for example?
