Strange error cannot figure it out on new installation V 3.0

[falves1]

My third node, all new, nothing running or installed on it, shows a red light and also if I click in Summary, it shows no CPU statistics. My node #2 is also empty and new, but it does not show the red light and it shows stats in summary. What am I doing wrong??

I rebooted my second node after adding a bridge, and the cluster web site shows no the same red light, and I cannot see any detail of the configuration. It is like if the node did not reconnect to the cluster How do I force it to reconnect?
