### Basic Information:

Printer Model:  
 MCU / Printerboard:  
 Host / SBC  
 klippy.log

_Fill out above information and_ **_in all cases attach your_ `klippy.log` _file_** (use zip to compress it, if too big). _Pasting your_ `printer.cfg` _is **not** needed_  
_ **Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there** _

### Describe your issue:

…sovols07  
it is not wanting to connect to the MCU While it was in the middle of a long print it stopped and said something about an update failing and to press firmware restart well i accidentally did reboot and it ended up stuck in the boot mode but i reflashed it and it was able to connect to the mcu and as soon as i started leveling it again it lost connection to the mcu ive looked everywhere for a solution. idk what to do. heres my klipper log

```auto
mcu 'mcu': Unable to open serial port: [Errno 2] could not open port /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0: [Errno 2] No such file or directory: '/dev/serial/by-id/usb-1a86_USB_Serial-if00-port0'

```

The key part is `No such file or directory: '/dev/serial/by-id/usb-1a86_USB_Serial-if00-port0'`  
Apart from the worst case, a defect board, you will likely find your reason here: [Issues flashing the printer board](https://klipper.discourse.group/t/issues-flashing-the-printer-board/14015)
