    I’m trying to connect to my PC using my Mac. Every time I connect to the PC, “The connection with the server was lost. Error is 54: connection reset by peer” pops up. Do anybody know how to resolve this issue?

    Also, I can’t connect to my Mac using my PC, the message was connection timed out.

    My PC is running Windows 8.1. My Mac is Mac OS X mavericks. I’m downloaded the official packages from the NoMachine website (https://www.nomachine.com/download) for both OS.

    I can’t connect to my Mac using my PC, the message was connection timed out.

    This is very likely a firewall problem. Try disabling the firewall or check that the firewall is not blocking port 4000 (this is the default port used by NoMachine).

    Every time I connect to the PC, “The connection with the server was lost. Error is 54: connection reset by peer” pops up.

    Logs would be useful for the problem connecting from Mac to Windows. We would need sets from both sides, so client logs from the Mac machine and server logs from the Windows PC. You can submit them here or send them to issues using the title of your topic.

    Instructions on how to gather logs are available here: https://www.nomachine.com/AR10K00697.

    The logs are in the attachment.

    Also, when I tried to connect to the same PC from Ubuntu, I got the same message “connection reset by peer”, except that the error code is different. I can connect Ubuntu from my Mac though.

    Can you send us the server logs from the Window host, too? These client logs are reporting a problem on the server, so we would need to see those. Enable logs on the server side, reproduce the problem and then send them on as you did before.

    1. Is the problem the same if you log in to another user?

    If ‘Bo’ is the only account on the server, try the following:

    – add a new account to the system (account must have password)

    – log in to it locally first

    – then log in via NX next

    2. Open cmd console and run the command below:

    $mkdir c:\tmp

    $cd “\Program Files (x86)\NoMachine\bin”

    $nxdisplay –homedirget –user Bo > c:\tmp\homedir.txt

    $net user Bo > c:\tmp\net.txt

    $wmic useraccount where name=’Bo’ get sid > c:\tmp\sid.txt

    and send files:

    – c:\tmp\homedir.txt

    – c:\tmp\net.txt

    – c:\tmp\sid.txt

    to us.

    3. Open regedit tool and search for the following key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\S-1-5-21-4284841049-3137553149-1734205093

    Does it exist?

    I created another user account in Windows 8.1, and it works!

    I was not able to get the homedir.txt file. When I run the “nxdisplay –homedirget –user Bo > c:\tmp\homedir.txt” command, it gave me some warning and error,

    “3888 5136 00:48:35 479.100 System/System: WARNING! Can’t open version file ‘C:\Program Files\NoMachine\etc\version’.

    3888 5136 00:48:35 483.100 System/System: Error is 2, ‘No such file or directory’.

    3888 5136 00:48:35 485.100 System/System: WARNING! Assuming version ‘4.0.0’.

    ERROR: Syntax error.”

     

    I found 3 folders that match part of the registry name, except their full names are :S-1-5-21-4284841049-3137553149-1734205093-1001,S-1-5-21-4284841049-3137553149-1734205093-1004 and S-1-5-21-4284841049-3137553149-1734205093-1005.

     

    the files are attached

    We have opened a TR for this bug.

    https://www.nomachine.com/TR01L04222

    We would also like some additional information:

    What is name of your Windows machine?

    Is it the same as username – Bo ?

    You can check machine name in control panel -> system -> right click -> properties.
