A DLP Cloud Detection Server (CDS) is not connecting to the Elastica CloudSOC (aka CASB), despite the CDS appearing as "connected" in Enforce.
Separately, an existing CDS for Email is not able to load any User Group indexes despite the Data Profiles being sent to other on-prem detection servers.
(There are not usually any errors when a Database Profile replication fails to be sent to a CDS.)
ALL indices for two-tier detection need to be completely error-free in order for Enforce to push any completed index up to a Cloud Detection Server.
Note that Directory Connections are also a form of Database Profile - with their filenames appearing just like EDMs in the Enforce "index" directory.
The example excerpt below shows a database profile for a Directory Connection which is successfully replicated to a DLP Detection Server.

DLP 14.6 or higher with Cloud Service for either Email or Application Detection
Cloud Detection Servers will not load indices for two-tier profiles if any of the profiles have corrupted indexes or missing files on re-indexing attempts. One corrupt index will prevent all indices from being loaded to the CDS, though this does not occur for on-prem Detection Servers.
