Hi,
last Thursday after an automatic update of the x2go-server our clients
didn't receive any more answer from the server. We had to switch to vnc
to get our workstations connected again. This morning, after an other
automatic update of the x2go-software, I noticed that clients could
connect again - but after an unacceptable delay of about 5 minutes. Here
our data:
We are on Ubuntu 16.04.3 LTSUbuntu 16.04.3 LTS
When starting x2goclient on a ubuntu client, after about 5 minutes it
shows the details:
NXPROXY - Version 3.5.0
Info: Proxy running in client mode with pid '25793'.
Session: Starting session at 'Mon Nov 13 18:28:30 2017'.

Now the client windows opens. To give more information about our
installation:
dpkg -l|grep x2go yields:

I extracted the relevant entries in syslog during that process. They are:

And looking for the processes with ps -ef|grep x2go at the beginning:

Is there somebody who could help us getting back to working
x2go-installation?
