Cause

• • Stale Credentials: The service account password was changed in vCenter/Active Directory but not updated in the Aria Operations credential store.
  • Certificate Trust: The vCenter Server certificate was renewed, but the new thumbprint was not accepted in Aria Operations.
  • Permissions: The account lacks the minimum required privileges in vCenter.
  • Format: The service account username was provided without the required domain suffix (e.g., username@domain).

Resolution

1. Confirm the account used for vCenter integration has the minimum required privileges in vCenter as per documentation Privileges Required for Configuring a vCenter Adapter Instance 
2. Log in to vCenter to confirm the service account is not locked or expired.
3. Navigate to Administration > Integrations > Accounts in Aria Operations.
4. Select the affected vCenter adapter and click Edit.
5. Click the icon next to the Credential dropdown to update the password.
6. Ensure the username follows the format domain\username or username@domain.
7. Click Validate Connection.
8. Click Accept if prompted to trust a new SSL certificate thumbprint.
9. Click Save.
10. Verify the adapter status changes to Data Receiving.
