Hi, thanks for taking the time to report this. There was a hitch with the manifest in the update server, but it has since been fixed 🙂 See these two topics for reference:
BritgirlKeymasterI don’t know which topic you are referring to but there are two similar ones open here:
Please follow either of those links for the Trouble Report.
BritgirlKeymasterThe config files are clean and the logs don’t show anything wrong with NX. The optimizations NoMachine can offer are within the session itself, not before webplayer has been fully loaded.
BritgirlKeymasterThe following Trouble Report has been opened:
Green screen when connecting by NoMachine client for Windows v. 6.10.12 to Ultra HD monitors
https://www.nomachine.com/TR05R09689BritgirlKeymasterFor everyone affected by the “green screen” issue please consult the Trouble Report we opened which contains further details:
Green screen when connecting by NoMachine client for Windows v. 6.10.12 to Ultra HD monitors
https://www.nomachine.com/TR05R09689BritgirlKeymasterrtsholiday, can you submit those logs to forum[at]nomachine[dot]com?
BritgirlKeymasterIf User A connects, and then another user WITH the same account connects, the session will migrate. NoMachine understands that the owner is connecting from another client and thinks it’s the same person.
Is it not possible for you to allocate an an individual system account to the users which need to connect? The default behaviour is that if UserA is connected to the remote computer, and UserB tries to connect, UserA will see a pop-up notifying them of the attempt. Only if UserA ignores the notification, they will be bounced off.
BritgirlKeymasterTom5, can you send us the user/.nx from your Windows Enterprise Client? Then from the Cloud Server host, send us the var/log. Instructions are here: https://www.nomachine.com/AR10K00697.
Then send everything to forum[at]nomachine[dot]com. Make sure you place the title of the topic in the subject. Thanks!
BritgirlKeymasterQ1: I was wondering how many connections can be made to the same machine at the same time? My understanding is just ONE for the free client. Please correct me if I’m wrong.
With the free version installed on the remote computer you want to access, one connection will be allowed at a time to that end point. On the connecting client, you can install either the free version or Enterprise Client, it’s up to you, and you can start as many connects as you want, but if you want to have more users connected to the same remote computer, that remote computer will require Enterprise Desktop. More details here:
What’s the difference between the free NoMachine package and Enterprise Desktop Subscription?
https://www.nomachine.com/AR02P00965Q2: If there is already a connection from a guest to host, does this preclude a second guest from logging on, or does the second guest disconnect the first – in essence bouncing the first user off?
The default behaviour is that if UserA is connected to the remote computer, and UserB tries to connect, UserA will see a pop-up notifying them of the attempt. If UserA ignores the notification, they will be bounced off.
BritgirlKeymasterThere was an issue with manifest causing a permissions error (for server-side installations), which has since been fixed so it is probable that you downloaded the update after we fixed it 🙂 You shouldn’t get the problem again.
To change the ownership back to nx, it’s enough to run the command:
sudo chown -R nx /usr/NX/var/db/limits

BritgirlKeymasterThis is a duplicate of this topic: https://forums.nomachine.com/topic/block-users-from-client-from-transfering-files
Change the system account of the connecting user to one with fewer permissions on the remote host, then they won’t be able to access the server/node cfg nor alter the settings in the server GUI. If the connecting user is an admin user, it’s impossible to prevent them from accessing the server preferences.

BritgirlKeymasterKurt, we’ve found what the problem is and our developers are looking into a possible solution. For some reason no confirmation that session is running is received from the agent, why this is I cannot say, this is what our developers are investigating. So, I am unable to give you an immediate workaround here. It is probable that we will need to send you a patched package, also with debug enabled. I or one of the developers will update the topic soon.
BritgirlKeymasterThe file didn’t attach, probably because it exceeded the max size allowed. Please send it to forum[at]nomachine[dot]com making sure you insert the title of this topic in the subject and indicate your forum nickname. Thanks!
BritgirlKeymasterPlease take a look at: https://www.nomachine.com/AR11L00827
The implementation of the upcoming feature NoMachine Network will make this type of intervention on the router and firewall unnecessary. You can read more about this here: https://www.nomachine.com/FR07J02731
