Can't get X2Go connection opened, with error PANIC! The remote NX proxy closed the connection.
In short: X2Goserver is hosted in Ubuntu 22.04 computer. It is being accessed from Ubuntu 20.04 and Windows 11. Previously, everything worked well, but today morning, I could not any more get connection to this computer, not from Ubuntu or from Windows 11.
On the Windows client error message is: "The remote proxy closed the connection while negotiating..." On Ubuntu client, x2goclient --debug print shows: --8<--8<-- RESUMING SESSION is KDRIVE: false x2go-DEBUG-../src/onmainwindow.cpp:6142> "Starting NX proxy, command: nxproxy -S nx/nx,options=/home/kalle/.x2go/S-ktuulos-50-1678441073_stDLXDE_dp24/options:50" x2go-DEBUG-../src/sshprocess.cpp:157> Direct tunnel: waiting for connections on "localhost":34744 x2go-DEBUG-../src/onmainwindow.cpp:6618> Proxy wrote on stderr: "\nNXPROXY uli42@gmx.de>\nCopyright (c) 2014-2016 Mihai Moldovan

On the Ubuntu 20.04 version, x2go package versions are the same, but openssh-server is version 1:8.2.
Could someone please instruct how to get this working? This Ubuntu 22.04 is my R&D work computer and I don't have a keyboard or monitor attached to it at all, so now I can only use it through the SSH terminal, which makes desktop operations pretty difficult. :(

Please try x2goclient --libssh-debug, maybe it shows more information.

Hi,
if you are not using kdrive then this message is totally ok.
The log does not show a real problem, AFAICS. So can you please try to configure a minimum session opening only an xterm, again without any file sharing, printing, sound?

In short: X2Goserver is hosted in Ubuntu 22.04 computer. It is being accessed from Ubuntu 20.04 and Windows 11. Previously, everything worked well, but today morning, I could not any more get connection to this computer, not from Ubuntu or from Windows 11.
On the Windows client error message is: "The remote proxy closed the connection while negotiating..." On Ubuntu client, x2goclient --debug print shows: --8<--8<-- RESUMING SESSION is KDRIVE: false x2go-DEBUG-../src/onmainwindow.cpp:6142> "Starting NX proxy, command: nxproxy -S nx/nx,options=/home/kalle/.x2go/S-ktuulos-50-1678441073_stDLXDE_dp24/options:50" x2go-DEBUG-../src/sshprocess.cpp:157> Direct tunnel: waiting for connections on "localhost":34744 x2go-DEBUG-../src/onmainwindow.cpp:6618> Proxy wrote on stderr: "\nNXPROXY - Version 3.5.99.23\n\nCopyright (c) 2001, 2011 NoMachine (http://www.nomachine.com)\nCopyright (c) 2008-2014 Oleksandr Shneyder <o.shneyder@phoca-gmbh.de>\nCopyright (c) 2014-2016 Ulrich Sibiller <uli42@gmx.de>\nCopyright (c) 2014-2016 Mihai Moldovan <ionic@ionic.de>\nCopyright (c) 2011-2016 Mike Gabriel <mike.gabriel@das-netzwerkteam.de>\nCopyright (c) 2015-2016 Qindel Group (http://www.qindel.com)\n\nNXCOMP, NX protocol compression and NX extensions to this software\nare copyright of the aforementioned persons and companies.\n\nRedistribution and use of the present software is allowed according\nto terms specified in the file LICENSE.nxcomp which comes in the\nsource distribution.\n\nAll rights reserved.\n\nNOTE: This software has received contributions from various other\ncontributors, only the core maintainers and supporters are listed as\ncopyright holders.

Printing, audio and shared folder have previously been activated and they have worked. Now I have disabled them and it does not make any difference.

On the Ubuntu 20.04 version, x2go package versions are the same, but openssh-server is version 1:8.2.
Could someone please instruct how to get this working? This Ubuntu 22.04 is my R&D work computer and I don't have a keyboard or monitor attached to it at all, so now I can only use it through the SSH terminal, which makes desktop operations pretty difficult. :(

Hi,
if you are not using kdrive then this message is totally ok.
The log does not show a real problem, AFAICS. So can you please try to configure a minimum session opening only an xterm, again without any file sharing, printing, sound?

Could someone please instruct how to get this working? This Ubuntu 22.04 is my R&D work computer and I don't have a keyboard or monitor attached to it at all, so now I can only use it through the SSH terminal, which makes desktop operations pretty difficult. :(

Hi,
again I don't see any major problem in libssh related output. But I see these:
qt.qpa.xcb: X server does not support XInput 2 qt.qpa.xcb: QXcbConnection: XCB error: 1 (BadRequest), sequence: 168, resource id: 309, major code: 130 (Unknown), minor code: 47
NX does not support XInput 2. So these errors indicate the session has been opened successfully but some application had a communication problem with the X server (x2goagent in this case).
So chances are that xterm, libxcb, libX11 or any accompanying library have been updated recently and are incompatible now. Maybe we can hunt this down by checking this: the nxagent window)
- ssh -X <server> and run "nxagent -D -ac :55" there (nxagent window should open up)
- ssh server and run "DISPLAY=:55 xterm" there (xterm should open in
Does the xterm come up?
Also please repeat with "nxagent -R -ac :55". (no nxagent window will come up, the xterm should open up in its own window in step 2)

Hi,
if you are not using kdrive then this message is totally ok.
The log does not show a real problem, AFAICS. So can you please try to configure a minimum session opening only an xterm, again without any file sharing, printing, sound?

Printing, audio and shared folder have previously been activated and they have worked. Now I have disabled them and it does not make any difference.
I have tried to re-install x2go server by command: sudo apt-get install --reinstall x2goserver x2goserver-common x2goserver-xsession
On the server computer, .xsession-x2go-<client>-errors file has following: --8<--8<-- XSession-x2go: X session started for ktuulos at pe 10.3.2023 11.30.25 +0200 dbus-update-activation-environment: setting DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus dbus-update-activation-environment: setting DISPLAY=:50 dbus-update-activation-environment: setting XAUTHORITY=/home/ktuulos/.Xauthority xrdb: Connection reset by peer xrdb: Can't open display ':50' /etc/x2go/Xsession.d/30x11-common_xresources: line 16: has_option: command not found xhost: unable to open display ":50" /etc/x2go/Xsession.d/75dbus_dbus-launch: line 9: has_option: command not found dbus-update-activation-environment: setting QT_ACCESSIBILITY=1 /etc/x2go/Xsession.d/90x11-common_ssh-agent: line 9: has_option: command not found dbus-update-activation-environment: setting SHELL=/bin/bash --8<--8<--

On the Ubuntu 20.04 version, x2go package versions are the same, but openssh-server is version 1:8.2.
Could someone please instruct how to get this working? This Ubuntu 22.04 is my R&D work computer and I don't have a keyboard or monitor attached to it at all, so now I can only use it through the SSH terminal, which makes desktop operations pretty difficult. :(

Hi Ulrich
NX Agent appeared and Xterm opened inside it.

Hi,
again I don't see any major problem in libssh related output. But I see these:
qt.qpa.xcb: X server does not support XInput 2 qt.qpa.xcb: QXcbConnection: XCB error: 1 (BadRequest), sequence: 168, resource id: 309, major code: 130 (Unknown), minor code: 47
NX does not support XInput 2. So these errors indicate the session has been opened successfully but some application had a communication problem with the X server (x2goagent in this case).
So chances are that xterm, libxcb, libX11 or any accompanying library have been updated recently and are incompatible now. Maybe we can hunt this down by checking this: the nxagent window)
- ssh -X <server> and run "nxagent -D -ac :55" there (nxagent window should open up)
- ssh server and run "DISPLAY=:55 xterm" there (xterm should open in
Does the xterm come up?
Also please repeat with "nxagent -R -ac :55". (no nxagent window will come up, the xterm should open up in its own window in step 2)

Thanks. So nx is working. To be honest I am out of ideas now. Have you checked what updates were installed on the server recently? Can you downgrade and retry?
