Hi Matt, Thanks for your reply. I'm using external zk and was using private IP in state.management.xml. Later, when i changed the log level to DEBUG, I got to know that nifi was unable to detect that IP. It was throwing Invalid IP address validation error. Figured out a way of passing public IP since we are going through company's proxy layer. It started working fine.
