Thanks for the suggestions.
Indeed, the behavior of nextcloud is a bit strange I was wrong it is not launched when the machine is turned on. The user launches it, but the interface disappear as soon as the mouse is moved away, but the application still run. It make difficult to interact with the application. Another call is necessary, and I get nextcloud.gui.application: Already running, exiting...
Are you using Gnome? If so, do you have the appindicator extension[1] or something like it installed? I vaguely remember the Nextcloud client just opening its little drop-down menu if the program is started with no system tray available. When that window closes, the program is left running in the background with no way for the user to get at it graphically. After installing a system tray extension, the client started working properly again. Things may have changed as the client seems to be better integrated into Gnome now, but installing the extension might be worth a shot anyway.
