Subscription to multicast in Windows is intermittent.?

I have already met with a problem: my app opens a connection and multicast packets arrive only during a certain time of 5-10 min. Then everything is dying. Wireshark shows that UPD packets with the desired IP addresses have stopped coming.
The output of `netsh interface ip show joins` confirms the subscription. And the number of links to that address (1). But Wireshark IGMP packets does not see, never to failure, or after. The word on systems where everything works fine? Shark shows packets IGMP membership report group are stable.
Prompt where to dig. Once on one of the computers helped pereustanovit Venda. This time this solution is unsatisfactory.
This is a problem with one computer but rather a single copy of the wends.

"Solved" by disabling IGMP snooping in the router. But this is not the solution.
"snooping in the router"? Something's not right here. - Jacquelyn_Kshler commented on July 9th 19 at 13:47
