Describe the bug
Multicasting do not work: I've created session, PCs were connected, session started, but nothing happens. All machines are in same local network, multicast supported.

Steps to reproduce the behavior:

1. Try to start multicast session

Hopefully this fix applied will correct the problem? Would you be willing to pull the dev-branch and test? Install is pretty simple generally.

but your fix looks better) I'll certainly try to switch to dev-branch tomorrow and report the results here.
