Partial functionality with Active IQ Unified Manager monitoring on a specific cluster

• Cluster appears to gather most inventory info, but acquisition shows Failed in Cluster Setup in AIQUM
• Performance data is not collected, resulting in a gap in the performance graphs
• ONTAP audit log gives Message (null) on HTTP from the AIQUM address
• In the sample.log under root within an acquisition recording or the ocumserver.log. Error: 
  WARN [oncommand] [reconciliation-0] [c.n.d.c.ClusterStatusListener] Acquisition Failed for cluster : <ip address> message : Cannot store non-PrivateKeys
• The cluster cannot be removed, throwing no error in the UI, and if attempted using um cli, it throws: ERROR: Cannot store non-PrivateKeys
• /opt/netapp/essentials/jboss/server/onaro/cert/aiqum_mtls_<cluster_name/IP>.keystore will not exist for the affected cluster if this is the issue being experienced
• ocumserver.log:
