Astrobox (RPi) dosn't find Marlin Printer animore

Hello,
everything has working fine till last week.
Now, after an update of my Raspberry-Astrobox Firmware, my printer is not recognised anymore.
When i plug the printer directly in my PC everything works. So i don’t think is a problem on the printer-side.

I don’t get it working. I just reinstalled my printers firmware, but its just the same.
Does anyone has an idea what i can do either?
best regards

Please enable serial logs in the advanced settings menu, try to connect to your printer and send us the logs.
