Windows vCenter 5.5 Update 3 and VMware vRealize Orchestrator 7.0.1 vapp. The vcenter webclient can not talk to the Orchestrator (so you can run workflows from within the web client and not vRo java client).
- Orchestrator can see the 5.5 vCenter in vRO WorkflowDesigner.
- Restarting the vcenter web client service and even the entire VC VM does not help
- vCenter plug-in (Home -> Configuration > Solutions/Client Plug-Ins) is enabled for vRO.
