• Hardware board : SKR Pro v1.2

• commit used (hash) (use the command git rev-parse --short HEAD): From lastest docker

Description of the problem:
Unable to connect to the Marlin board & send GCode to it
When I click on connect, SandyPi tells me I'm connected, but when I try to send GCode, nothing is added (via the manual control tab).

I'm able to command the board and the ZenXY via my PC and using Pronterface using 250000
I'm also able to connect the Marlin board via a OctoPrint setup on another Raspberry using /dev/ttyACM0
.
And I was also able to send Gode command to it
