Wyse ThinOS 9.1.3129 on 3040 disconect disconnects after 30 minutes of inactivity

Hi

After upgrade from ThinOS 9.1.2101 to 9.1.3129 Wyse disconnects after 30 minutes of inactivity.

The wise 3040 with ThinOS 9.1.2101 has no problems. After upgrade to ThinOS 9.1.3129 the think client disconnects after 30 minutes, returning to the logon mask.

In wyse I use the Citrix APP 21.6.0.28.2 package. I checked all the timeout parameters passed by the Wyse Managemnt Suite but they are ok, and they work fine in ThinOS 9.1.2101.

Is it possible that ThinOS 9.1.3129 uses Citrix Delivery Control parameters?
