Cannot run Klipper FLSUN SR

I am at the end of the Klipper install directions for FLSUN SR and I am launching fluidd interface. I am getting an error message that first says

  • “Printer is not ready The klippy host software is attempting to connect. Pleaseretry in a few moments.”

But then after a few retry’s after a few moments, I get this

  • “mcu ‘mcu’: Unable to connect Once the underlying issue is corrected, use the"FIRMWARE_RESTART” command to reset the firmware, reload theconfig, and restart the host software. Error configuring printer"

I am very much at a loss here…
