UP, I 've the same problem.
NTP : OK
certificates: OK
vCenter 5.1.1
vCO applaince: 5.1.1
No firewall
Works with my first vCenter, but not not with the second, error 400. vCenter are identical, same architecture, same version.
I don't understand why. I tried with http on second vCenter, but error 301.
Do you think i can purge configuration about the second vcenter in vCO ? (not just delete server), delete all information in vCO ?
Any help would be greatly appreciated...
