The customer is attempting to enroll 2 or more Cloud Detection Servers (aka "Detectors"), and at least one of them was provisioned for a different region (US vs EU).
Although the first enrollment will be successful, and show as Connected, when the second Detector is added it does not appear to complete, and the first Detector goes into a "Disconnected" state.
"The bundle refers to a Gateway different than the one that has already been configured."
Enforce, and bundles for 2 or more Cloud Detection Servers
Enforce can only register Cloud Detection Servers from one global region, e.g., US or EU.
The error occurs when a second enrollment for a second region is attempted, and Enforce is thereafter denied access to connect to any Detectors via the Cloud Service Gateway.
If this has happened, it will be necessary to confirm which region is required - US or EU, and to re-provision whichever Detector(s) were incorrectly provisioned (requires ticket with Cloud Operations team). A new bundle will also be required for any Detectors which were previously enrolled and connected (i.e., re-enrollment to force association with the correct region).
