We are building vRA 7.3 . We added vCenter and NSX manager as endpoint in vRA. And associate NSX manager with vCenter. All of computing resource data collection works well but not NSX (network and security):

So in vRA reservation, we only can see vSphere cluster, vDS port-group/logical switch but not Transport zone, security group/tags

When check the log, we see the following:

Workflow ‘vSphereVCNSInventory’ failed with the following exception:

One or more errors occurred.

Inner Exception: An error occurred while sending the request.

at System.Activities.CodeActivity.InternalExecute(ActivityInstance instance, ActivityExecutor executor, BookmarkManager bookmarkManager)

at System.Activities.Runtime.ActivityExecutor.ExecuteActivityWorkItem.ExecuteBody(ActivityExecutor executor, BookmarkManager bookmarkManager, Location resultLocation)

Inner Exception:

I tried to delete NSX end point and recreate from vRA but no luck. I raised the issue in vmware community but can’t get any real valuable feedback.

After a few hours investigation, finally I find a fix:

run the “create a NSX endpoint” workflow in vRO as the below

Then I re-start network & security data collection in vRA. Everything works and I can see all defined NSX Transport Zone, security groups and DLR in vRA network reservations.

Hope this fix can help others who have the same issue.
