Out of the Blue unable to connect to mcu...

Ok.. i'm at a loss as to what happened and why. I have a Rat 500, all metal hotend and I printed 2 or 3 things yesterday, including mount for the BTT SFS V2.0. I hooked up the new SFS, plugged it in as shown in the document. All seem's good, the Dashboard showed the sensor and showed it had filament. I decided to check if I had any updates that were needed before starting a print...there were a couple so i applied them and now I can't get the pi to connect to the mcu, but yet, when i go to the http://ratos.local/configure?step=1 and in the upper right hand side and under Moonraker I choose flash all attached MCU's and it goes through and flashes and says successfuly flashed attached 1/1 mcu. I reboot and still the problem is there. Here is what log file is showing. Any help is greatly appreciated mcu 'mcu': Starting serial connect mcu 'mcu': Unable to open serial port: [Errno 2] could not open port /dev/btt-octopus-11: [Errno 2] No such file or directory: '/dev/btt-octopus-11' webhooks client 548140481792: New connection webhooks client 548140481792: Client info {'program': 'Moonraker', 'version': 'v0.8.0-204-gfb15b2a'} mcu 'mcu': Unable to open serial port: [Errno 2] could not open port /dev/btt-octopus-11: [Errno 2] No such file or directory: '/dev/btt-octopus-11' MCU error during connect Traceback (most recent call last): File "/home/pi/klipper/klippy/mcu.py", line 800, in _mcu_identify self._serial.connect_uart(self._serialport, self._baud, rts) File "/home/pi/klipper/klippy/serialhdl.py", line 182, in connect_uart self._error("Unable to connect") File "/home/pi/klipper/klippy/serialhdl.py", line 61, in _error raise error(self.warn_prefix + (msg % params)) serialhdl.error: mcu 'mcu': Unable to connect During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/home/pi/klipper/klippy/klippy.py", line 176, in _connect self.send_event("klippy:mcu_identify")

For quicker replies you should move this to fix my printer or better yet Ratos support rather than fix my print.
