Issue accessing Fluid and SFTP

Hi all I have the K1 MAX and having major issues.

It refuses to let me into fluid coming up with a login screen and despite me typing the root and creality_2023 it refuses to allow me in.

I also can SsH into printer to root prompt but if I use the same app and try to access files which I have always done using SFTP won’t connect.

I have tried factory reset

Reinstall fluid

USB BURN TOOL method and all have same issue, is it worth me buying another printer because it clearly isn’t working

Have you installed moonraker.
Moonraker is an API interface that is required by Fluidd or Mainsale to access klipper.

I found this video helpful in setting up my K1c. With easy steps to install moonraker, Fluidd and other apps.
