Cause

The error is caused by an expired or invalid authentication session/credentials between VMware Cloud Director and the AVI (NSX Advanced Load Balancer) controller, leading to API failures (NsxAlbApiException) when fetching logs beyond cached data.

Resolution

1. Log in to the VMware Cloud Director Provider Portal as a System Administrator.
2. Navigate to Infrastructure Resources from the top navigation menu.
3. In the left pane, under NSX-T ALB, select Controllers.
4. Select the target AVI Controller from the inventory list and click Edit.
5. Re-enter the admin credentials for the AVI Controller and click Save.
6. Verify the controller status and version display correctly in the VCD UI.
