This happens also if you start by attaching to node1, then you disable
node 1 and it fails over to node 0 and everything is fine?
but when you fail back to node 1 again after enabling it you have an outage?

Can you please send me the output of netstat -a -n on all three hosts
client, node0 and node1 before you disable node0, after you have
disabled node0 and after you have re-enabled node0 again and have the
issue.


Oh,   can you verify that you have IPv6 completely disabled?
