There’s no inherent reason why this shouldn’t work, but I suspect that
(somehow) you lost multicast routing when you switched to using a static IP.
To check this, run
netstat -r -n
and check whether you have a route for 224/8
You might be able to fix this by running (as root):
route add 224.0.0.0/4 ip-address-for-that-nic
