    I checked my remote computer that the NX server is enabled:
    NX> 111 New connections to NoMachine server are enabled.
    NX> 162 Enabled service: nxserver.
    NX> 162 Enabled service: nxnode.
    NX> 162 Enabled service: nxd.
    NX> 162 Enabled service: nxhtd.
    However, I still encounter the problem that could not connect to the server. Here is the full log:

    Hi carolyc,

    Can you tell us if you’re setting a proxy in your player configuration? Thanks!

    Hi Carin,

    Thank you for your quick reply. You are right I haven’t set my proxy.

    However, after I enabled the auto-proxy discovery(Mac OS), I still encountered the error (see attachment).
    My remote computer is Ubuntu.

    Hi carolyc,

    It looks like the file failed to attach. Do you mind sending it directly to forum[at]nomachine[dot]com? Please add the title of the topic in the email subject. Thanks!

    Hi carolyc,

    Can you send us your player configuration (.nx directory) and session file (.nxs file)?  Please remove the stored password in the .nxs file. Thanks!

    Hi, is this problem solved?

    I also had this same problem. My situation is NoMachine with zerotier, this error 22 occurred when I enable  proxy no matter I chose “use system configuration“ nor “automatic configuration” even the LAN connection would show this error message, but if I uncheck the proxy, every connection is normal.

    I’ve deleted these attachments for your own security – it’s always best to remove saved credentials when sharing such files in a public forum. We’ll get back to you soon on what the problem could be.

    Hi. The error printed by the client is misleading, it should have stated clearly that there is a problem with the proxy configuration. We’ve documented this wrong error reporting here:

    https://www.nomachine.com/TR07S10321

    As for the reason why the proxy configuration is wrong, this is not clear yet. Can you try to select “Use system proxy setting” instead of “Automatic proxy configuration”? Is your system actually configured to use a proxy?
    If you’re not sure about it but you know proxy parameters, you can select the manual configuration and fill it with the correct proxy host and port.
