Vmware NSX and VMware NSX-T Data center.
The issue happens due to stale Transport Node Collections, which could be a result of deleting the clusters directly from the vCenter server without proper NSX configuration.
This issue is resolved in VMware NSX 3.2.2 and 4.1.1.0, available at Broadcom downloads. If you are having difficulty finding and downloading software, please review the Download Broadcom products and software KB.
