<div class="moz-cite-prefix">I may have found my own answer when I
finally got to see the session detail below. It led me to a post
describing how the session data on a server can get corrupted. My
only question: how can 14 servers in different locations get
corrupted all at the same time? Here's what I've run to fix 2 of
the 14 servers so far:<br>
<br>
<pre class="message"> $ sudo rm -f /var/lib/x2go/x2go_sessions
$ sudo x2godbadmin --createdb</pre>
Hopefully, I won't need to post about this issue again and maybe
this information will be helpful to someone else.<br>

fails, if I can catch it before it totally closes out and goes
back to the login and then click on session details. I get this:<br>

<p>Greetings,</p>
<p>I sent this yesterday, but was not a member of the list, so
wasn't sure if it would end up being approved and posted or
not. Here's the content of that message and I apologize if
this is a duplicate:<br>
</p>
<p>We use x2go extensively for some access to some Ubuntu based
LTSP servers. Suddenly over the last two days, we get the
following in the client:</p>
<p>"The remote proxy closed the connection while negotiating<br>
the session. This may be due to the wrong authentication<br>
credentials passed to the server."</p>
<p>And on the server we are trying to connect to, we see this in
the logs:</p>
<p>/usr/bin/x2goresume-session: client [ip.address.of.client]
has successfully resumed session with ID
kscadmin-51-1520534328_stDMATE_dp24</p>
<p>/usr/bin/x2gosetkeyboard:
/home/ksca0dmin/.x2go/C-kscadmin-51-1520534328_stDMATE_dp24/keyboard
did not appear within 30s after agent startup</p>
<p>We are never able to connect. This happens even on all
servers that we connect to and includes older server versions:</p>
<p> x2goagent: 3.5.0.33<br>
x2goserver: 4.0.1.22<br>
x2goserver-extensions: 4.0.1.22<br>
x2goserver-xsession: 4.0.1.22</p>
<p>As well as newer ones:</p>
<p> x2goserver: 4.1.0.0<br>
x2goserver-common: 4.1.0.0<br>
x2goserver-extensions: 4.1.0.0<br>
x2goserver-fmbindings: 4.1.0.0<br>
x2goserver-printing: 4.1.0.0<br>
x2goserver-x2goagent: 3.5.99.14<br>
x2goserver-xsession: 4.1.0.0</p>
<p>Unfortunately, the clients are now updated as well trying to
fix this issue, but they were failing on the older client
version as well:</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px;
margin-right:0px; -qt-block-indent:0; text-indent:0px;"><span

(Qt - 4.8.7)</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px;
margin-right:0px; -qt-block-indent:0; text-indent:0px;"><br>
</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px;
margin-right:0px; -qt-block-indent:0; text-indent:0px;">Any
help would be appreciated.</p>
