Alessio, It looks like the flow is the not the same on both nodes. Since you only have two nodes, NiFi is not able to come up with a majority of votes. Specifically, it looks like the conf/authorizations.xml or conf/authorizers.xml or conf/users.xml file is out-of-sync. You can try copying these from 1 node to the other, or just deleting them from 1 node and it will inherit the other node's on startup.
