Creality Ender 3 connection

I have installed 3DPrinterOS on a RaspPi 3 b, but it never connect to my Ender 3. I have an SKR Mini E3 installed on the Ender 3. The logs show it connecting to the printer but failing. Has anyone been able to use 3DPrinterOS with an Ender 3?

Did you ever find a fix to this issue ?
