If you are connecting to the physical desktop of the remote machine, you can set the following key in the in the node configuration file (/usr/NX/etc/node.cfg) on the server side to auto-disconnect after a specific amount of time.
DisplayAgentExtraOptions “-timeout 600”
For reference, check this article: https://kb.nomachine.com/AR01H00551
Are you able to send us the logs so we can check them? You can extract them using the instructions here: https://kb.nomachine.com/DT07S00243. It would be useful to have both the client (step 4 in the document) not just server side logs.

We had a similar report a while back, you could be encountering the same problem. It is Raspberry which is reporting the wrong information. In checking the latest image of Raspberry Pi OSarmv7 (Bookworm), there is a 64-bit kernel. This is why uname -m command shows aarch64. However, the libraries in Bookworm are for armv7 and so you could try installing a NoMachine package for armv7.
Hello, we already do. Supported key types in NX and SSH connections are RSA, DSA, ECDSA and ED25519. For web connections, the RSA key type is supported.
Hi, are these all Mac machines? It would help to know the exact OS version of the computer you are connecting from when you experience this and to which OS version you are trying to reach.
Q1- Where can I find the fingerprint on the server to check it ?
openssl x509 -noout -sha256 -inform pem -fingerprint -in /usr/NX/etc/keys/host/nx_host_rsa_key.crt
Q2- Could you confirm all is OK with this manual procedure ?
Yes, it is a standard procedure to pre-configure client’s hosts.
Understood. The name given there is actually the name of the session file. In the current version, the name of the connection is displayed in the caption instead of the hostname or the name of the node. This is the standard default behaviour across all products. To distinguish among the nodes you could create one connection for each node, give it the node name and save it. Be sure to check the ‘Save the selected node in the connection file’ option.
For a future version we already have planned the possibility to add the option to display the node name in the client window caption with Cloud Server set-ups. On the basis of your requirements, should it be optional or should it be the default standard?
The caption could be something similar to this:
<session name> (<node name>) - NoMachine <session name> (<node name> via <CS name>) - NoMachine (for multi-level only, show node parent name)I imagine this would this satisfy your requirement, but if you have another idea, by all means we will be happy to evaluate your suggestion.
NoMachine is not a password manager. Stored credentials are scrambled and you can read more about this in the following article: https://kb.nomachine.com/AR01C00125
maxim-nomachine, can you send us the server-side logs so we can check them? You can extract them using the instructions here: https://kb.nomachine.com/DT07S00243. Send them to forum[at]nomachine[dot]com. Please use the title of this topic as the subject of your email. Thanks!
The -head and -tail extracts were useful. What we see is that all the networking resources (such as socket handles) get an error at the same time. Can you check whether there are any antivirus, anti-malware, security system that may be interfering? When the problem occurs, the NoMachine Player process remains in the background instead of closing (so it continues to log, hence the big logs, both nx session and the log node session logs show the same thing by the way and we’ll see what improvements can be made to mitigate this). It should be easy to understand whether disabling the “security system” or adding NoMachine Player among the exceptions helps.
You wrote:
added the pubkey to the “authorized.crt” file in %USERPROFILE%/.nx on the host Windows machine
it should be .nx/config. Maybe this is the problem? Can you follow the instructions for How to set up key based authentication with NX protocol in this article https://kb.nomachine.com/AR02L00785?
Is it possible there is some trivial error like a typo in the file name, or even wrong permission?
You can also send us the logs from both player and server machines. You can extract them using the instructions here: https://kb.nomachine.com/DT07S00243. Send them to forum[at]nomachine[dot]com. Please use the title of this topic as the subject of your email. Thanks!
