Hello everyone, after weeks of running, I suddenly have the issue, that the camera doesn't take pictures from time to time. This is what's happening in the log:

Any ideas how to fix it? I'm using a ZWO ASI678MC

The most common reason for this is a bad connection to the camera. I would try to re-seat the USB connection. If that does not work, you could also try a different USB port.

If that does not work, you probably need to replace the USB cable.
