<font face="Helvetica, Arial, sans-serif">Hi,<br>
<br>
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:<br>
We are on Ubuntu 16.04.3 LTSUbuntu 16.04.3 LTS<br>
When starting x2goclient on a ubuntu client, after about 5 minutes
it shows the details:</font><tt><br>
