Stopping at random points mid print

I have repetier server installed and controlling 6 printers.

OS is windows 10, I have a GEEETECH A10 (Ender 3 clone) that keeps stopping mid print. It worked fine for weeks, I'm not sure why it keeps stopping.

The end of the printer log when it happens is:

Any help would be appreciated.

    Windows closed the com port and it came back 4 seconds later as I see from the log. So that explains why the server stopped. Did the print continue? Guess not because I see "start" and reset was triggered.

    So the real question is why did windows close the port. You should check windows events around that time to see if there are any events com related and hopefully there is a reason you can understand. On a pi I would have said power problems but not that likely on windows. You might try covering 5V pin on usb as described here:

    Just in case it is because the printer draws more than allowed and that is why windows disables it. That way printer needs to take it from own power.
