It looks like there could be some problem with audio interface and it crash. Did you change anything recently related to audio interface?
Could you try to disable audio?
To do this please edit as admin file:

C:\Program Files (x86)\NoMachine\etc\node.cfg

Find line:
AudioInterface
Uncomment it if it is commented already and set disable:
AudioInterface disable
Then restart NoMachine.

Yours db looks ok, so the problem is somewhere else. I saw your logs but they are only from ProgramData directory and we need also enabled logs from

C:\Users\%USERPROFILE%\.nx\

You can enable logs manually, and then restart NoMachine with command

nxserver --restart

started in cmd which is run as Admin in directory

C:\Program Files (x86)\NoMachine\bin\

You can also enable logs with a command from cmd
https://knowledgebase.nomachine.com/DT10O00163#1.5
here is an article explaining how to do it, and then also restart NoMachine.

Then you need to gather logs, I prefer the method described here:
https://knowledgebase.nomachine.com/DT10O00162#1

Important for me are logs:
%USERPROFILE%\.nx
because looks like on your machine node is started but it closes immediately.

@mymachines
Looks like the update went wrong on your installation.
There are a few options:
1) Reinstall NoMachine:
-Simply remove NoMachine, restart the machine, install a new one and restart the whole computer should help.

2) Check if the file:

C:\Program Files (x86)\NoMachine\etc\nodes.db

exists. (if there is nodes.db.backup or .orig, simply rename it and continue)
If yes, then run “cmd” as Administrator, go to directory:

C:\Program Files (x86)\NoMachine\bin\

and run

nxserver --updatedb

and then

nxserver --restart

3) If the above file does not exist
then run “cmd” as Administrator
go to directory

C:\Program Files (x86)\NoMachine\bin\

and run debug command

nxserver --addtoredis

and then

nxserver --restart

Could you please send us the file:
C:\Program Files (x86)\NoMachine\etc\nxdb
from that Windows?

It will help with the investigation. Thanks!

[og00r]

The logs don’t indicate anything odd. If we send you special packages with added debug, would you test it and send us result?

[og00r]

Please check in the process explorer if it is running nxservice.exe or nxservice64.exe also check if in task manager in tab “services” nxservice is running.

If all the above are running please enable logs one more time and send them on the forum. To do that you need to follow the instructions here: How to gather debug logs for support requests.
I guess there is no problem with the license reading but I don’t see if the main server is starting (you send disabled logs and they don’t tell much).

Thanks!

I received only logs from client side, after reinstall. But there is error:

Failing reason is ‘The remote host ‘192.168.1.102’ refused to establish a network connection on port ‘4000’. Please verify that NoMachine is correctly installed and listening on the port where you are trying to connect, and that incoming traffic is not being blocked by a firewall or NAT.’.

are able to ping that machine (192.168.1.102) from one where nxclient is?
Are you sure that ports 4000 and 4001 are open in firewall? Or they are forwarded in dynu dns?

[og00r]

Could you try to change the path in key UserNXDirectoryPath in node.cfg to some directory where everybody has access? Could be something temporary as /tmp/

Second question is, are you using AD domain? Or is it some kind of LDAP configuration?
How it is configured?
Could you try to provide login in the format:
DOMAIN\username

[og00r]

Could you please also upload log files from that redirected path?
Also is there any nx logs (.nx) in user STAFF/myair (for example) home directory?
I am missing files from his side, as it looks until that moment everything works ok, something is wrong on their side, and such logs should be in redirected path or in that user home directory.

[og00r]

I saw some problems with domain users home directory:
3360 7248 11:28:15 542.364 HostHomeDirGet: ERROR! Cannot retrieve home directory for user ‘TD-EF\myair’.

could you try change path in key UserNXDirectoryPath in node.cfg to some directory where everybody got access? Could be something temporary as C:\tmp\

And if problem persist we would need more information like:
– is every user affected?
– at what step it crashes? After login?
– do you using nfs drive maybe?

[og00r]

Ok, looks like some problem with starting the main process, as I do not see any logs from it on restart.
I guess you restarted already the whole machine a few times and it still happens. Could you try to make a fresh install?
Delete C:\Program Files (x86)\NoMachine after uninstall. Then reinstall again without activating licenses (they should be activate since installation).
Also, ensure that the computer is correctly restarted after the installation process.
Are you using some external firewall/antivirus which could block NoMachine processes?

Did you forward correct ports in that Dynu DNS?
Here is an article with the ports NoMachine needs:
https://www.nomachine.com/AR01L00770

Did you try back to setup without Dynu?

[og00r]

Ok thanks for last outputs.
As I’m trying reproduce issue, but please in meantime paste here output of:
nxserver –subscription run also in cmd as admin.
nxserver –version run also in cmd as admin.

and paste yours server.lic if possible. As it looks like problem with get correct product id from it.

[og00r]

I hope that you restarted whole operating system after installation?

[og00r]

Could you try my solution from this post:

Cannot get output for command: evalsha after resending

that one with sudo /etc/NX/nxserver –updatedb
or
with fresh reinstall and remove /usr/NX

If nothing helps, please let me know.

[og00r]

Are you sure that NoMachine nxserver is not running? I see some nxserver process in process explorer.

But lets find out:
1) Open cmd as admin.
2) go to C:\Program\ Files\ (x86)\NoMachine\bin
3) run command “nxserver –status”
4) if it is disabled then run “nxserver –restart”. (I hope machine was restarted after installation)
(double click on nxserver.exe does nothing as nxserver requires parameters for every operations, so all further commands must be done through cmd with correct parameters “–something”)

Please paste here screenshot with output for command from point 3 and point 4.

Also I do not see logs from nxserver or even nxinstall, could you check those both location for them:

C:\ProgramData\NoMachine\var\log\
C:\Users\YourUsername\.nx\

There should be (nxinstall.log / nxupdate.log and nxerror.log and nxserver.log). Collect them please.
