    Hi everybody,

    I am trying to connect to from a Windows 7  Computer to an Ubuntu PC (on Nvidia Jetson AGX Xavier), which is constantly failing. It always gives a timeout error.

    From the session log (please see attached file) I get this information:

    ‘6576 7112 13:04:56 834.036 ClientSession: Runnable at 0x04dfc2e8 caused the session at 0x02bf8a50 to fail.’

    Does anyone know what this means?

    As far as I know, there is no Firewall on my ubuntu-PC. Maybe the problem refers to some NAT-blocking?

    On my Ubuntu-PC I there are three different IPs listed (two both wirh NX and SSH, one just with SSH).

    In contrast, I can connect frim my Ubuntu-PC to my Windows-PC.

    I am thankful for any ideas.


    Hi LordCalvin,

    Can you please send us the logs by e-mail to forum(at)nomachine(dot)com, making sure you reference the topic as subject.

    If needed, the procedure to gather logs is explained here: https://www.nomachine.com/DT10O00163

    Furthermore, could you please also tell us the Ubuntu version you are using, the NoMachine version & protocol you are trying to use, and explain the network setup of Ubuntu as you mention about being behind NAT.

    Thank you in advance
