Flsun V400 moonraker

Good evening everyone
I don’t know if I’m right here, I have a question and a problem, I’ve had my first Klipper printer FLSUN V400 for 3 weeks) After the last update I will get this error message. Since I am still new to the Clipper area, one of you could tell me how I can solve the problem. I have already read on the Internet that you should change the Moonraker CFG, but I don’t know how to change the CFG or what to change there, so you could help me with this problem

Hello @Blackdevil !

What error message?
