We are trying to set up a 3 node nifi cluster on GCP virtual machine (Ubuntu). Have used a CA signed certificate for creating truststore and keystore (Followed this link for creation). Have attached them through nifi.properties file. Still getting below exception on tailing logs: 2022-05-26 18:14:26,544 INFO [main] o.a.n.c.p.AbstractNodeProtocolSender Cluster Coordinator is located at nifi-hostname:7474.
