I apologise for not answering earlier. It is solved with the indication of Majkl. I uninstall NX on the client side, remove all “nx” & “nomachine” directory, install it again and it is working.
I see 2 times the same share, but it is not a big deal.
I didn’t really need to use that option until last november. I remember it was working or at least seeing remote drive without any configuration on server side.
I can send you the old & new client side directory if needed.
Thanks to you both
