OK, so the missing multicast messages would have followed this route:

Kinsky[PC] -> Ethernet cable > upstairs router -> Airport Extreme -> Airport Express -> downstairs switch -> MinimServer[QNAP]

I will look at the log file to see what it reveals. What are the IP addresses of the Kinsky PC and the QNAP?
