Hi, I'm using Pega 7.3.0 and have loaded prsysmgmt. I've configured my 2 clustered nodes. When I click on the links on the left, they load fine but the moment I load High Availability Management, I get the below error and subsequently all the links fail. In the SMA guide (https://pdn.pega.com/products/system-management-application-sma) version 6.3 SP1 (the latest version), there is no mention of High Availability Management under the Administration Chapter. Am I missing out on anything?

MSG:

com.pega.jmx.ui.util.JMXClientException: Node: x.x.x.x Exception: com.pega.jmx.ui.util.JMXClientException:
