Two node can't see each other.

Hi!

I got a problem.
I was sutted down the 2 node at night. And when i'll started the nodes can't see each other. But its not correct, the nodes can ping each other in separated ring but in cluster it show as red.
I restarted the full nodes many time but the error still here.

It seems multicast don't work.
