Ian thank you very much for the help.
I found the problem.
When an automated failover take places, the repmgr process on the failed
node dies.
Postgresql service stops on Node1 , Node2 is promoted as master
automaticaly, but repmgr on node1 stops, and I need to start repmgr again
after recover Node1.
Is this the expected behavior?
Regards.

Is repmgrd running on node1? Is its repmgr.conf file configured correctly,
e.g. "failover=automatic"
