Environment

VCF Operations 9.x

Cause

This issue occurs because the data collection for the specific vCenter Server has stopped or is in a "Failed" state  in VCF Operations

Resolution

To resolve the issue:

1. Navigate to Administration → Integrations → Accounts in VCF Operations.

2. Identify the affected vCenter adapter instance.

3. Verify the adapter status and resolve any data collection issues:

   • Fix certificate validation errors (re-trust certificate if required).

   • Validate credentials.

   • Ensure network connectivity between VCF Operations and vCenter.

4. Confirm that data collection resumes successfully and the adapter status changes to healthy/collecting.

5. Once data collection is restored, retry the license assignment by following the steps outlined in the “Assign a Primary License to a vCenter Instance” documentation.
