Hi All
I have the exact same problem after upgrade from 5.1 to 5.5. The yellow bar show the "https://domain.local:443/sdk" error when I use the administrator@vsphere.local or domain admin. Further more, the path should be "https://vcenter.domain.local:443/sdk" with the computer name in front of the domain name. And cannot see any inventory.
However, no problem with the vsphere windows client.
Regards
