If you cannot connect to a server directly through Horizon Client, or if your desktop and application entitlements are not visible in Horizon Client, Workspace ONE mode might be enabled on the server.
Beginning with Horizon 7 version 7.2, an administrator can enable Workspace ONE mode on a Connection Server instance.
When Workspace ONE mode is enabled for a Connection Server instance, you can connect to the server only through Workspace ONE, and you can open remote desktops and applications only through Workspace ONE. This behavior is normal when Workspace ONE mode is enabled.
