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 ?
