    Hello,

    I am having problems connecting from my home Windows computer to an Ubuntu computer at my university. After connecting a few times with no problems, I then come to connect again and get a connection timeout error:

    A connection timeout has occurred while trying to connect to ‘132.68.58.21’ on port ‘4000’. The issue could either be caused by a networking problem, by a firewall or NAT blocking incoming traffic or by a wrong server address. Please verify your configuration and try again.

    This is a recurring problem. Sometimes restarting the host computer solves the problem, but then after some time, it happens again.

    The logs I get (on the client side):
    Info: Starting NoMachine version 7.1.3.
    Info: Loading settings from 'C:\Users\erans\.nx\config\player.cfg'.
    Info: Loaded translation files for 'English'.

    Hi erans,

    Can you also send us logs from the server-side, please?
    You can see the following article for guidance: Collect server and client logs manually
    Please send as an attachment to forum[at]nomachine[dot]com making sure you use the title of the topic in the subject of your email. Thanks!

    Erans, can you tell us which university’s facilities you are connecting to and have you asked your administrator for further assistance if this is a set-up arranged for your faculty?
