Cannot deploy organization VDC network : VSM respo...

"Failed to publish configuration on vShield Edge. The requested object : {some object} could not be found."

This kind of error occurs when vshield manager (Network & Security Manger) loses connection to vCenter server. If you try to redeploy a vshield edge device you will get an error saying "vshield manager cannot connect to vCenter"

All that has to be done - reconnect vCenter Server to vShield manager. (Can be done in vshield manager web ui on configuation tab)

A restart of the vshield manager, vshield Edge or redeployment of vshield edge might also be required.

The root cause of this error in my case was the fact that I updated SSL certificate of vCenter.

So when reconnecting i had to accept new fingerprint.

Onother possible reason - the username/password of the user that vshield mgr uses to connect to vCenter. If password has been changed or the user has been deleted -  a new credentials still can be supplied during "vcenter reconnection procedure"
