So I first tried reinstalling x2goclient and it did not work, even
with an *apt-get
purge* , deleting the *session* file in ~/.x2goclient/ and rebooting the
server.

Then I finally noticed something :

   - the connection did not work from my Laptop (which is of course, the
   one from which I need it to work) : Linux Mint 18 with x2go client 4.0.5
   - the connection worked from an old Windows 7 with x2go client 4.1.1
   - it also worked from a Debian 9 with x2go client 4.1.1

The version of x2go installed on the server is 4.1.0.

So it made sense to try installing the latest stable x2go client version.
After checking, I ahd indeed not added the ppa to the software sources and
was using the version from the Linux Mint repositories.

So I did that and now it works.

Shall I ask something to the wiki ?
