I hope you are well. I have recently been suggested to try NoMachine as an VNC alternative, but am having issues changing the Server Preferences. When I try to enable changes and input my admin username or password, it errors saying “Authentication failed, please try again”. I know the password is correct, as MacOS credential prompt accepts it and does not “shake” like is usually does with an incorrect input. I have tried this with an domain user as well as a local admin user.
I am using NoMachine 6.11.2 with MacOS Catalina 10.15.6. Any assistance would be greatly appreciated.

If you’re sure it’s not a case of wrong username and password, then we need to see the .nx folder of computer you are trying to change preferences of. You can find it in the user’s home (under /User/username) . Attach it here or send it to forum[at]nomachine[dot]com making sure you include the title of your topic in the subject.August 14, 2020 at 08:41 #28990
Definitely the right username and password, as I used the same credentials to authenticate the installtion of NoMachine. I’ve sent the .nx folder in a zip file to the email address specified.

Logs show the following:
Cannot get information for group id '23636965' Warning: Could not open for writing settings file '/Users/davidn/.nx/config/player.cfg'.
– What is group 23636965?
– Check your access rights to server side folder .nx/config and file player.cfgAugust 17, 2020 at 07:50 #29009
The 23636965 is a domain group. Regardless, even if I apply 777 permissions to the config folder and its contents, I am still unable to authenticate to change the settings.

Is your home folder located on a remote filesystem (mounted by NFS, for example)?August 18, 2020 at 13:17 #29028
No, it’s local to my machine.August 24, 2020 at 07:29 #29089tUdspaGeParticipant
I’m also having this issue on latest Catalina and latest NoMachine version.August 25, 2020 at 15:09 #29133graywolfParticipant
Would you send the output of command
sudo -l -U davidn?
Would you try a debug version of a NoMachine component in order to collect more information?August 26, 2020 at 07:55 #29140
sudo -l -U davidn

We received the logs, thank you.September 17, 2020 at 08:08 #29501tUdspaGeParticipant
Any solution to this issue found? Bc it’s not accepting the password, I’m not able to uninstall the application.September 18, 2020 at 08:55 #29513CatoParticipant
What are permissions of /Applications/NoMachine.app/Contents/Frameworks/bin/nxexec file? Correct permissions should look like this: -r-sr-xr-x.
