NSX Federation 4.x
Workaround 1:
Trigger a full sync between the Local Manager & Global Manager
POST https://<Local-NSX-Manager-IP>/policy/api/v1/infra/full-sync-action?action=request_full_sync
Workaround 2:
Perform a rolling reboot of the Local Managers followed by the Global Managers.
If this does not work, open a case with Broadcom support and select the vDefend Firewall or NSX firewall product.
