a while later and without doing ANYTHING, MONA has returned to work on the auto switch, and I repeat I have not touched anything, nor restarted the computer nor the program nor the rig.
Sometimes this happens and I stop for a miner, I had to create a rule that if a miner is 2 minutes standing, start mining. But these random failures are very annoying. Thank goodness that the video is to show that I'm not crazy.
The error in your video indicates that when the mining software was about to be started it either failed to start or crashed right after being started. Please use the Diagnostics button in the toolbar when this happens to see the details of what's going on and any error message from the mining software.
