Unable to add cluster data source. This can occur if the clocks on the systems are not synchronized and the Active IQ Unified Manager HTTPS certificate start date is later than the date on the cluster, or if the cluster has reached the maximum number of EMS notification destinations.
Still getting this error after seeing that the clock systems were fine. The HTTPS cert on UM expires 2026 while the cluster HTTPS cert expires on a later date, 2027. The EMS notification was increased to the suggested amount (5) via: Active IQ Unified Manager fails to add ONTAP cluster due to a breach of max number of EMS notification destinations - NetApp Knowledge Base
Not sure why I'm not able to add any cluster to Active IQ UM.
