Siril-cli with no display

Hello. I have a server running with Ubuntu which I use for computation tasks, and thus have good performance. I would like to use it for stacking my images, but I access to it via ssh, it is not connected to any display/screen. I installed Siril and I tried running the cli with scripts, but I am getting the next error:

Unable to init server: No se pudo conectar: Conexión rehusada

(siril-cli:596640): Gtk-WARNING **: 18:52:28.365: cannot open display: 

I am trying with these commands:

siril-cli -s ~/siril/scripts/OSC.ssf 
siril -s ~/siril/scripts/OSC.ssf 

Output of siril -v: siril 1.2.6

Output of apt show siril:

Description: astronomical image processing tool
 Siril is an image processing tool specially tailored for noise reduction and
 improving the signal/noise ratio of an image from multiple captures, as
 required in astronomy. Siril can align automatically or manually, stack and
 enhance pictures from various file formats, even images sequences (movies and
 SER files).

Is there any way to run the scripts or commands without a display via the command line?

Hello, siril-cli -s ~/siril/scripts/OSC.ssf is supposed to be working, there is possibly a bug somewhere, we’ll have to check, thanks

It works for me
