Can you further explain your connection issues? Is it specific to Edge Appliances?
Would it be possible to power down the secondary node, or disable HA? This error has been reported by someone using a previous verison: Vshield Edge error message on vCloud environnement
Do the errors reference only vm-200 and vm-201? Are those all Edge appliances? Another thought would be to use the redeploy option on the edge appliances.
Is the registration to vCenter, in the NSX Manager UI, also green?
