A DLP Enforce environment previously configured (in v14.6 or earlier) with a Cloud Connector is no longer detecting incidents for registered Securlet or Gatelets after upgrade.
There are 2 possible causes.
Firstly, there is a known defect when 2 servers for Cloud Detection are registered in the same Enforce console. This issue usually arises after the second one is added, and is described in TECH248993 (see related articles link). The solution in that case requires upgrading to 15.0 MP1.
This article describes a second issue - which is related to the configuration of individual Gatelets or Securlets in the "Manage > Application Detection" fields.
Much of the backend as well as the UI changed in DLP v15 - as per related article content.
DLP v15, upgrading from earlier release (14.6, 14.6 MP2, etc.)
If the configuration of an app for detection is not correct, no "syncing" of the Application Detection will occur.
Below are 2 examples of incorrect details for O365 Securlet, for instance:
Settings as entered when "Sync Pending" never resolves:
See this screenshot for depiction of 3 correctly configured O365 Securlets:
Once the configuration is saved, the synchronization should commence without further action required.
