Thinwire Error: Thinwire unknow command:0xff, previous=0xc2

[Simon Abplanalp]

Hello 

 

In our environment, we have since the beginning of September the following message sometimes appering: Thinwire unknow command:0xff, previous=0xc2

We have our VDA, NetScaler and Delivery Controller on the newest Version. Before it worked over month, without these message. We can't really find any Logs to it, neither in the Win Event Viewer nor in the Citrix Logs. 

 

This error appears only on Andorid Devices, Windows Computers on the same Terminal Servers work without this error. The Workspace App on the Android devices are 20.9.5. 

 

Any advice or similar experience to this?
