Hello,
it seems that you don’t have a desktop environment installed, or nxnode doesn’t find it.
In this case, this article could be helpful: ‘How to solve error ‘Cannot find the default environment’ on Linux headless machines’ (https://www.nomachine.com/AR06N00891)
If you have a correct and existing command set in DefaultDesktopCommand
key in node.cfg, then please enable logs in server and node, restart the server
and connect using the client.
Reproduce problem, collect logs and send them to forums[at]nomachine[dot]com using
“Unable to access remote centos 7 server” as e-mail’s subject.
The procedure to collect logs is available here: https://www.nomachine.com/DT07M00098
