Hi RadioFred,

Can you please send us logs from both client and server sides. From the server side we need debug logs. We will need you to enable debug, restart nxserver and then reproduce the issue and collect the logs.

You can see the following article for guidance: https://www.nomachine.com/DT11R00181&dn=logs#1.4.

Please send them directly to us via email to forum[at]nomachine[dot]com and we will take a look. Please use the title of this topic as the subject of your email. Thanks!
