Creality CR-10 Smart Klipper Firmware with internal Creality Box

Good Day

I need help please

I tried to reinstall mainsail then decided to install fluid as i have problems where klipper stops responding and my prints fail

Now i cant get fluid to open in my web browser but the luci interface still works. It’s as if the web services for fluid is broken or not installed.

How do i do a clean install on the creality wifi box?

My Printer is a CR 10 Smart (Not the Pro)
