Why does bitcoin mining randomly stop on multipool?

[FlutterPie]

The reason I stopped mining at multipool for a while was because bitcoin mining would randomly go down for hours at a time. My miners would stop mining, and that is just loss of profit. I just checked my mining stats on multipool, and it shows I am mining at 0 Mh/s.

I thought it was a problem with my miners, so I checked on them, and they are still mining. So what is the problem actually?

They probably switched to a more profitable coin. That's what a multipool does.

Are you sure your miner had not failed over to a backup pool?
