you're using UDP discovery on the client. I would check the Broadcaster on the servers.
Do you really need UDP on the client though? it's usually easier to connect to a node and get the topology from that node. Say (DNS). but if you must use UDP, check your configuration. perhaps the broadcaster is sending an IP the client cannot understand.
