I've installed the vRP 7.3 applicance (VMware-vRO-Appliance-7.3.0.21553-5521409_OVF10.ova) but it is unable to accept the certificate from my vSphere 6.5 instance:
Error! An error occurred while retrieving the Single Sign-On token from: https://10.2.53.90/lookupservice/sdk
Any ideas? Is 7.3 knowsn to work with vSphere authentication?
