View 6.01 - Mac Client - You are not entitled to use this system

Hi All,

Running a View 6.01 (test) environment with two hosts, one the Connection Server and One RDS host.

Its a published app only. One App only.

All configured and licensed. Local access at the office works fine both on the Windows and Mac client..

When connect to environment remotely (via an sslvpn which has full access to internal LAN) I experience the following error:

MAC Client - You are not entitled to use the system. (see screenshot)

The Windows client works as fine.

Its just the MAC client causing the error. Mac OS is Yosemite 10.10.3 and the Mac Client 2.3 (1551379)

Any advice would be appreciated.

Thanks
