I've had exactly the same errors, and eventually found what was wrong.
The problem seems to be the vlans, switches which block the multicast
traffic. For now I'm using a crosscable.

So, check with the network engineers, they should be able to assist you,
but you can convince them they're blocking you using the crosscable.
