The server was unable to make the local display available

Dear NoMachine community

thank you very much for having spread at some degree of usability your nice server-client system for desktop&file sharing.

On my machine cluster (ca. 6 machine) I am thinking of using NoMachine instead of teamviewer or remote desktop (all macs and a linux machine). Now today concretely:

I installed from the latest on two remote sites (A and B) NoMachine 5.3.9 – both sites have OSX Sierra.

After having installed your nice server program (NoMachine free edition) on both sites and having opened ports, disabled firewalls, also me is getting the now famous warning (and no connection defacto):

The server was unable to make the local display available or access to the local display is disabled.

That costed me today already three hours of web searching, blogging, and I have to see that also other mac users have the same issue… so we found a way to distantiate us or is it now a method to submit you machine-after-machine the own connection logs 😉 ?

It seems you did not find any solution yet, so the thought whether to switch to the paid industrial version could be put in doubt … ?

Thank you also for solving this (…) new problem 😉

Regards

Hello redskate,
we are not able to reproduce such problem in our lab. Could you please enable debug restart
nxserver and send us logs if you can reproduce the issue ?

You can find instructions about debug and collecting logs here: https://www.nomachine.com/DT07M00098.

I have the same problem.  My logs are attached.

Thanks,

Jim Gish

Dear jwgish,

thank you for logs. Unfortunately nxserver was not restarted, so these logs
don’t provide the necessary information to investigate the problem.

Please restart the server, you can do that from a console by running:

sudo /etc/NX/nxserver –restart

Then reproduce the problem (message: The server was unable to make the local display available or access to the local display is disabled.)

Collect and send us the new set of logs.

Additionally, please give us also the following information:

1) OSX version

2) Device type (e.g. Macbook Pro)

3) If a user is physically logged-in to the desktop or if there is the Login window.

4) If advanced configurations are set, e.g. LDAP etc…

Regards
