Yes, you can and should use company signed certs. Ask your company/Admins/infoSec to give you truststore and keystore jks files with passwords. Add these files in nifi.properties along with password. Restart Nifi.
Hi @Umair Khan I am getting this error when using CA signed certs:
o.a.n.c.c.node.NodeClusterCoordinator Failed to determine which node is elected active Cluster Coordinator: ZooKeeper reports the address as F.Q.D.N:9088, but there is no node with this address. Attempted to determine the node's information but failed to retrieve its information due to org.apache.nifi.cluster.protocol.ProtocolException: Failed to request Node Identifer from F.Q.D.N:9088
