Hello everybody!
I confront with strange issue.
Subj is only on Linux machine.
Desktop Xfce4 (Linux Mint 17)
Display manager MDM (earlier was LightDM, when was working fine, before update)
$ uname -a
Linux ixy 4.4.0-109-generic #132-Ubuntu SMP Tue Jan 9 19:52:39 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
$ /usr/NX/bin/nxserver –version
NoMachine – Version 6.0.66
On client I see clear white window.
After fews minutes, on client occured message error 138: Timeout.
I tried client on Windows 7, Android. Is result same.
On server which described above is:
in /usr/NX/var/log/nxerror.log

More concrete error, sounds as “NX> 500 Error: Cannot find environment for process xfce4-session xfce4-session’
I investigated the call so bad next parameter “xfce4-session xfce4-session”.
There expect like “1234/1234” because it is $PROCESS_ID.
What is proccess id? How I can find out it?
About those warnings there is such problem described here:
https://www.nomachine.com/TR12O08309but problem should not affect conenction to session, only some mess in logs.
Can you please paste output of “ps -ef | grep X”?Is there any warning during nxserver –restart?
During connection there was question about creating new display because nomachine did not find any?
Or it just white window after connection without anything?If it is second option can you check client logs?
These logs are located on machine where nxplayer is used, in user home directory. For example you say, that tried connect from windows.
To find it, write the following in the address bar or the file browser:
%USERPROFILE%\.nx
As an alternative, you may navigate through the computer folder till the user’s home and digit .nx in the navigation toolbar to reach this hidden folder.
Path can be similar to: C:/Users/nomachine/.nxAbout those warnings there is such problem described here: https://www.nomachine.com/TR12O08309
Similar as my problem, txh .. will see it.
Can you please paste output of “ps -ef | grep X”?

Is there any warning during nxserver –restart?
During connection there was question about creating new display because NoMachine did not find any?
Or it just white window after connection without anything?No warning. Was no question.
Just white … you can to look video.
When I did as recommended in Trouble Report https://www.nomachine.com/TR12O08309.
I was seeing such screen.
No available sessions on this server
You should not use workaround from this TR, because it removes physical session from connection options.
27645 27677 11:37:09 255.702 TcpListener/Listener: WARNING! Refusing connection from ‘192.168.132.2’ port 39***.
Warning: Refusing connection from ‘192.168.132.2’ port 39***.Looks like there could be problem with loopback for localhost when you connect. Do you have any changes in network configuration?
Standard name for loopback in Linux is lo:
ip addr show dev loI have similar problem with another application based on java stack.
In that case i had have error “refused connection” (in gradle plugin for IDEA).
I need to investigate my OS in details. It seems they are related…
@molokovskikh, it’s worth checking the loopback configuration as ‘og00r’ suggested. Let us know what you find.
