Experiencing an issue with LwIP in a network with an IGMP snooping switch. The switch is not an actual multicast router, so it sends general membership queries with a source address of 0.0.0.0. This appears to be in line with RFC 4541, however LwIP discards the packets due to the bogus source address. This causes the IGMP code to never respond with a membership report and the switch to stop forwarding multicast packets on that port.
