[X2Go-User] X2Go Client suddenly failing to connect

[Ivan Gomez]

One new update on this issue:

Updated x2gosever on one of the servers that was showing the issue to x2goserver-4.0.1.22-2.el7.x86_64. After the update, access through that server started working again.

Any guidance to understand the root cause would still be greatly appreciated.

Thanks,
Ivan G.

Hi Mihai,



Here is output from rpm -qa | grep -iE '(nx|x2go)'



libNX_X11-3.5.0.32-3.el7.x86_64

libNX_Xcomposite-3.5.0.32-3.el7.x86_64

libNX_Xdamage-3.5.0.32-3.el7.x86_64

libNX_Xdmcp-3.5.0.32-3.el7.x86_64

libNX_Xext-3.5.0.32-3.el7.x86_64

libNX_Xfixes-3.5.0.32-3.el7.x86_64

libNX_Xinerama-3.5.0.32-3.el7.x86_64

libNX_Xpm-3.5.0.32-3.el7.x86_64

libNX_Xrandr-3.5.0.32-3.el7.x86_64

libNX_Xrender-3.5.0.32-3.el7.x86_64

libNX_Xtst-3.5.0.32-3.el7.x86_64

nxagent-3.5.0.32-3.el7.x86_64

nx-libs-3.5.0.32-3.el7.x86_64

x2goagent-3.5.0.32-3.el7.x86_64

x2goserver-4.0.1.20-1.el7.x86_64



One additional detail that we discovered after further troubleshooting:

We have multiple backend servers running X2go. All servers have identical output of rpm -qa | grep -iE '(nx|x2go)', but currently 2 of them present are stuck in this state where applications won't launch while a third identical sever is not showing issues.



Thanks!

Ivan
